TOI-1338: TESS’ First Transiting Circumbinary Planet
Published in The Astronomical Journal, 2020
TOI-1338 b is the planet that I helped to discover in the summer before my senior year of high school while I was working with Dr. Veselin Kostov at NASA Goddard Space Flight Center. I was searching through targets identified as Eclipsing Binaries on the citizen science project Planet Hunters TESS when I noticed an interesting target.
Below is the original lightcurve that I saw– the dip between day-14 and day-15 is the primary eclipse (i.e. when the smaller star blocks the light of the bigger star) and the smaller dip between days 15 and 16 is the planetary transit.

- Discovery of TESS Mission’s First Circumbinary Planet by Dr. Ravi Kopparapu – My advisor from the previous summer and secondary advisor that summer
- A teenager discovered a new planet on the third day of his NASA internship by the Washington Post
