2. REMINDER: 2025 Sagan Summer Workshop Silver Jubilee: Exoplanet Demographics (July 21-25, 2025) and PROfessional Tools and Opportunities (PROTO) Workshop (July 20, 2025)

2025 Sagan Summer Workshop
Silver Jubilee: Exoplanet Demographics
July 21-25, 2025
Hosted by The NASA Exoplanet Science Institute
California Institute of Technology, Pasadena, CA
https://nexsci.caltech.edu/workshop/2025/
#sagan2025

and

PROTO Workshop
Sunday, July 20, 2025
(optional, half-day PROfessional Tools and Opportunities (PROTO) Workshop)
https://nexsci.caltech.edu/workshop/2025/proto.shtml

The topic of the 2025 Sagan Summer Workshop will be the "Demographics of Exoplanets," and will address the contribution of each of the major planet-finding techniques to our overall knowledge of the architectures of exoplanetary systems. Along with presentations about each technique and its particular strengths and biases, the Workshop will address the synthesis of these results into a complete demographic picture for comparison with models of the formation and evolution of planetary systems. The Workshop will explore gaps in our knowledge and how future missions and surveys will address them. Of particular emphasis will be the importance of a full demographic picture, including the incidence of Earth-sized planets in the Habitable Zones of their host stars, to future missions such as the Habitable Worlds Observatory.

The 2025 Sagan Summer Workshop will be the 25th in this series of workshops (https://nexsci.caltech.edu/conferences/#workshop). In addition to the demographics of exoplanets, this "Silver Jubilee" will also address the demographics of Workshop attendees over time, with a presentation and discussion of their career trajectories.

The 2025 workshop will be hybrid, with both in-person and remote attendance. The Sagan Summer Workshops are aimed at advanced undergraduate students, graduate students, and postdocs; however, all are welcome to attend. There is no registration fee for these workshops.

2025 PROTO Workshop:

Preceding the 2025 Sagan Summer Workshop, the optional add-on, half-day PROfessional Tools and Opportunities (PROTO) Workshop will take place on July 20, 2025. This Workshop will cover the nuts and bolts of becoming an exoplanet astronomer, offering a how-to guide for getting exoplanet science done, rather than focusing on what the science is. Geared toward the early-career community, this Workshop will be an interactive session that encourages students to contextualize what they learn throughout the Sagan Summer Workshop, and translate it to getting involved. By providing a venue for discussion of otherwise hidden or undiscussed topics, the PROTO Workshop aims to reduce barriers that limit participation in the exoplanet community through all career stages, from student to professional scientist.

This workshop will be a hybrid meeting, and all are welcome to attend. Students unfamiliar with the path to becoming an astronomer and/or NASA missions are particularly encouraged to register. PROTO registration uses the same form as the 2025 Sagan Summer Workshop, You can register for both the Sagan Summer and PROTO Workshops using this link: https://catcopy.ipac.caltech.edu/ssw/registration.php

6. Rogue Worlds 2 Conference (December 15-17, 2025; Paris)

Rogue Worlds 2
December 15-17, 2025
IAP, Sorbonne University / CNRS, Paris
https://indico.iap.fr/event/47/

"Dear Colleagues,

This December 15-17 (2025), you are cordially invited to Paris for Rogue Worlds 2, the second in the Rogue Worlds series of meetings (talks from the first meeting available here). It will be a 3-day workshop focusing on the detection, dynamics, and astrophysical interpretation of free-floating planetary mass objects.

Registration and abstract submission are open on the website: https://indico.iap.fr/event/47/

(If you encounter any difficulties, please contact rogueii-loc@services.cnrs.fr )

Scientific rationale

Free-floating, or "rogue", planetary-mass objects have been discovered wandering through the Galaxy unbound to any star. The origins of these objects remain poorly understood, and likely involve a combination of many different processes relevant to star and planet formation. Direct imaging surveys of young star-forming regions have already found hundreds of high-mass rogue planets, though it remains an ongoing theoretical challenge to determine what fraction represent ejected planets as opposed to aborted stellar embryos. Meanwhile, upcoming microlensing missions such as the Nancy Grace Roman telescope are poised to vastly increase our sample of free-floating planets at masses extending to Earth-mass and below, opening a new window into their origin and demographics.

Rogue Worlds 2 is a 3-day workshop designed to bring together researchers at the forefront of different aspects of the study of free-floating planets, including microlensing (ground- and space-based), direct imaging, and modeling of stellar and planetary dynamics. The format of the workshop is designed to promote discussion and foster collaboration, bringing together researchers across a wide array of fields to make new progress on our understanding of rogue worlds and the systems they leave behind.

Invited speakers:

• Takahiro Sumi (Microlensing detection of free-floating planets)
• Scott Gaudi (Update on the Nancy Grace Roman space telescope)
• Nuria Miret-Roig (Direct imaging of free-floating planets)
• Malena Rice (Dynamics of planetary ejection)
• Amaya Moro-Martin (Connecting free-floating planets and interstellar objects)
• Ruth Murray-Clay (Connecting free-floating planets with the tail end of the stellar IMF)

Scientific organizing committee: Sean N. Raymond (LAB/CNRS) (chair), Hervé Bouy (LAB/Université de Bordeaux) (co-chair), Jean-Philippe Beaulieu (IAP/CNRS), David P. Bennett (UMD/NASA Goddard), William A. DeRocco (UMD/JHU), Jackie Faherty (AMNH)

2. ExoPAG SAG 25: Technosignature Proposal Survey (Feedback requested by July 24, 2025)

“Hello members of the ExoPAG!

I am messaging you on behalf of the Technosignature SAG. The Technosignature SAG (operating through the ExoPAG) is a group of volunteer experts in technosignatures/SETI who are producing a report to NASA’s Exoplanet Exploration Program. This report will contain the results of its analysis on how NASA can better integrate technosignature searches into its portfolio.

I wanted to reach out with an opportunity to provide data for the report. One of our working groups is currently collecting data on how and where technosignature proposals are currently being submitted, with an eventual goal of suggesting changes to the proposal process to make technosignatures a more integrated and rigorous part of NASA's solicited science programs.

We want to invite you to fill out a survey about your experiences with submitting technosignature proposals (https://tinyurl.com/TechnosigProposalSurvey). We would like to hear your perspective even if you have never led a technosignature proposal, or even submitted one. We are looking for responses about US-based funding sources, especially those provided by NASA. The survey should take only 5-10 minutes to complete.

Please let us know if you have any questions. We intend to close the form on Thursday, July 24th, so please make sure you have submitted your feedback by that date.

Thank you, we look forward to hearing your experiences!
Sofia Sheikh"

2. Input Requested for 2026 ExEP Science Gap List (Input Requested by September 30, 2025)

The NASA Exoplanet Exploration Program (ExEP) is seeking community input on the ExEP Science Gap List (SGL) through September 30, 2025, with the goal of providing an updated version in early 2026:

The current 2025 version of the SGL is posted on the ExEP Program Science page: https://exoplanets.nasa.gov/internal_resources/3193/ExEP_Science_Gap_List_2025.pdf

The Science Gap List (SGL) curates from community inputs program “science gaps”, which are defined as the difference between knowledge needed to define requirements for specified future NASA exoplanet missions and the current state of the art, or knowledge which is needed to enhance the science return of current and future NASA exoplanet missions. This gap list is a resource for the broader community, pointing to where focused science investigations are needed over the next 3-5 years in support of community ExEP goals. The ExEP Science Gap List represents activities and investigations that will advance the goals of NASA’s Exoplanet Exploration Program, and provides brief summaries in a convenient tabular format. The ExEP Science Gap list is meant to assist proposers in describing the relevance of their work to Program goals as they respond to SMD ROSES and mission observing proposal solicitations. All ExEP approaches, activities, and decisions are guided by science priorities, and those priorities are presented and summarized in the ExEP Science Gap List.

UPDATE: You can submit your suggestions either anonymously or with your name and email via the new Google form at: https://docs.google.com/forms/d/18-QkF1PXc8YgZ-X3KLy18MmgcwRmeNBuLYa9up-2wys/

For any questions on the ExEP Science Gap List, you are welcome to contact ExEP scientists Karl Stapelfeldt (Karl.R.Stapelfeldt@jpl.nasa.gov) & Eric Mamajek (Eric.Mamajek@jpl.nasa.gov).

3. 2025 ExoExplorer Science Seminar Series (June 13, 2025, 2:00pm-3:00pm EDT / 11:00am-12:00pm PDT)

The final session of the 2025 ExoExplorer Science Seminar Series will take place on Friday, June 13, 2025, from 11 AM - 12 PM Pacific / 2 PM - 3 PM Eastern.

The June speakers are:

Samantha Hasler (MIT)
Title: Using Orbital Phase and Atmospheric Composition to Discriminate Reflected Light Observations of Exoplanets

Abstract: Future direct imaging missions, including the Roman Space Telescope and the Habitable Worlds Observatory, will enable the detection of exoplanets in reflected light. However, these observations may present unique challenges including planet-detection confusion in multi-planet systems and uncertainties in characterization. I will present two of my PhD projects which are focused on addressing these issues. First, I address the planet-detection confusion problem by augmenting a “deconfusion” algorithm with planetary phase variation and photometric properties to support orbit differentiation in multi-planet systems. This work demonstrates the necessity of combining relative astrometry and photometry to reduce confusion rates. Second, I will present an analysis of high phase angle observations of Uranus from the New Horizons mission to provide a ground-truth for interpreting exo-ice-giant observations. Together these efforts support robust, informed expectations of exoplanet brightness and atmospheric variations, which are critical for informing yield modeling, instrument design, atmospheric modeling, and observation scheduling for future direct imaging missions.

and

Ben Cassese (Columbia University)
Title: The Challenges of Detecting Planetary Oblateness, and TESS's View of the Solar System

Abstract: In this somewhat disjointed two-part talk, I'll give an overview of the two in-progress halves of my thesis work. In the first half I'll discuss the prospects for and our attempts to detect planetary oblateness, or deviations from spherical symmetry, with current space-based facilities like JWST. Though this measurement is technically feasible, the miniscule size of the signal necessitates careful consideration of modeling choices, especially that of which limb darkening parameterization to use. I will propose a new framework for this: fitting directly in stellar parameters such as effective temperature and metallicity, rather than a potentially non-physical law. In the second half, I will discuss my work on using TESS to discover Trans-Neptunian Objects and how to quantify the impact of unresolved solar system objects on exoplanet transit searches.
