Molly Simon
Dr. Molly Simon (she/her)

Education: BS in Geophysical Sciences from UChicago, PhD in Planetary Science from Univ. of Arizona - LPL

Occupation: Assistant Professor in the School of Earth and Space Exploration at Arizona State Univ.

What do you do on Exoplanet Watch? I created and teach and online research course for undergraduates that utilizes tools from Exoplanet Watch to update the ephemeris of a new target each semester. I also co-mentor several undergraduates alongside folks at Exoplanet Watch on projects spanning from ephemeris maintenance and ground-based observing to planetary detection.

Why do you work on Exoplanet Watch? I'm a big believer in the power of citizen science and how it can be used to make research accessible to a broad population of learners. It is a fun experience to realize all we can do with small, ground-based telescopes when it comes to making an impact on exoplanet research

Heath Rhoades - Table Mountain Astronomy Team Lead

Occupation: Optical Telescope Systems

What do you do on Exoplanet Watch? “I build and maintain control software/hardware observing systems for the 1.0m, 0.6m, 0.4m and “Gizmo” 6” telescope array at the Table Mountain Observatory. Using these systems I am observing exoplanet transits on most clear nights, analyzing and uploading into the AAVSO database.”

Why do you work on Exoplanet Watch? “In the more than 20 years I have been working at Table Mountain supporting astronomical campaigns, the Exoplanet Watch program has been the most fun and rewarding.”

Bradley Hutson - Undergraduate Intern

Education: Associates of Applied Science in Meteorology; BS in Astronomical and Planetary Sciences (Arizona State University)

Occupation: USAF Meteorology

What do you do on Exoplanet Watch? "Focusing on integrating archival RV data and feature the in-depth study of a single target as a proof of concept to centralize and standardize RV data for easy access for all in the future in one location. Using this information to update the ephemerides and eclipse timing for future ARIEL and JWST observations."

Why do you work on Exoplanet Watch? "It is literally the 'What I want to do when I grow up' (even though I'm already in my 30s). I've been interested in astronomy for the last 20 years and did astrophotography in my off time and even tried to get some light curves before Exoplanet Watch. When a research opportunity through ASU appeared, I jumped at it to finally be able to do some work that could be useful instead of just astrophotography in my off time, and it has continued from there. It is as close as we can get to exploring the universe until the USS Enterprise is built in 220 years."

Occupation: Retired

What do you do on Exoplanet Watch? "I am collaborating on a team with participants from Arizona State University and NASA/JPL to refine exoplanet ephemeris using citizen science transit data from Exoplanet Watch and professional terrestrial and space observatories, along with radial velocity data from public archives. The techniques developed within this team can allow all Exoplanet Watch users to use radial velocity data to refine the ephemeris they create from their transit observations. I am also interested in using future astrometry data (specifically from the Vera C Rubin/LSST observatory after operations begin in 2025) to complement Exoplanet Watch transit observations as we have done with radial velocity data."

Why do you work on Exoplanet Watch? "Citizen science and AI are likely the tools of the future, providing the horsepower to discover and refine the ephemeris for exoplanet research as more targets are added to the inventory. The Rubin Observatory is an example of a source that will contribute massive amounts of data to astronomy archives. The future will bring more of these sources. Professional astronomers and astrophysicists will benefit greatly from partnering with citizen scientists to explore the observations and data that are produced in ever-increasing amounts."
