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."

Suber Corley
Suber Corley - Student Intern

Education: BS in Physics; BS in Astronomical and Planetary Sciences

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."

Why do you work on Exoplanet Watch? "I find global cooperation inspirational -- the idea of citizen scientists and professional astronomers all over the world coming together to help us understand our expansive cosmos is incredibly romantic to me. As a science fiction writer and astrophysics student, I've always been moved and fascinated by the worlds beyond our own and the physical laws by which they're governed. Joining Exoplanet Watch has been a truly remarkable experience in that it oversees star-enamored communities coming together to work toward a common goal of education, innovation, and cooperation."


Federico Noguer
Federico Noguer - Undergraduate Intern

Education: Majoring in Astronomical and Planetary Science with minor in Physics

Occupation: Undergraduate Researcher

What do you do on Exoplanet Watch? "In collaboration with Arizona State University and NASA/JPL I analyze citizen science transit data along with archived data from large ground and space telescopes to refine the ephemeris of exoplanets. Additionally, we include eclipse and radial velocity data to constrain the parameters of exoplanets. One such study has lead to publication with citizen scientists Exoplanet Watch members as co-authors. I also utilize large telescopes like the 61-inch Kuiper telescope and the 200-inch Hale telescope at Palomar Observatory for follow-up transit observations. Current research involves validating and confirming exoplanet candidates through proposed radial velocity observations and follow-up transit observations. Long-period planets with Earth-like orbits in particular excite me. Some of these candidates have only two transits, making period determination challenging. By analyzing existing data, we can predict possible orbital periods for these planets and forecast future potential transit dates for observation. The network of Exoplanet Watch observers can utilize their own telescopes to help find these transits. After graduating from Arizona State University, I plan to pursue a Ph.D. program and dedicate my career to exoplanet research."

Why do you work on Exoplanet Watch? "Working on Exoplanet Watch has been a personal and professional privilege. Interacting with the Exoplanet Watch community has been immensely fulfilling, allowing me to connect with people around the country and the world who share a passion for exoplanet research. As a non-traditional scientist who worked as a concrete mason for most of my life, I strongly believe that ANYONE is capable of participating in frontline research with drive, determination, and a little help. I have been fortunate to work with a team of exoplanet research professionals who have helped me grow both personally and as a scientist. I hope to carry the torch and do the same for others."


Dr. Tara Fetherolf
Dr. Tara Fetherolf (she/her) - NASA Postdoctoral Program Fellow

Education: BS in Astronomy (San Diego State University), PhD in Physics with an Astrophysics Emphasis (University of California, Riverside)

Occupation: NASA Postdoctoral Program Fellow

What do you do on Exoplanet Watch? "I help identify and account for the effects of stellar variability in the observed light curves of known and candidate exoplanets. Stellar variability that is unaccounted for can lead to false positive exoplanet detections and incorrect planet radius measurements. Stellar variations related to the star’s rotation can also reveal information about the age of the exoplanetary system."

Why do you work on Exoplanet Watch? "There are so many small pieces that contribute to the larger puzzle of characterizing an exoplanet. Understanding the host star’s variability is just one of those pieces, but it’s amazing to see how many pieces are fulfilled through the work of many members throughout the Exoplanet Watch collaboration. I also really enjoy working with and mentoring students and community members who are enthusiastic about astronomy, science, and Exoplanet Watch!"
