Jitter Across 15 Years: Leveraging Precise Photometry from Kepler and TESS to Extract Exoplanets from Radial Velocity Time Series
Corey Beard, Paul Robertson, Jack Lubin +24
Stellar activity contamination of radial velocity (RV) data is one of the top challenges plaguing the field of extreme precision RV (EPRV) science. Previous work has shown that pho…
Searching for GEMS: Two Super-Jupiters around M-dwarfs -- Signatures of Instability or Accretion?
Andrew Hotnisky, Shubham Kanodia, Jessica Libby-Roberts +20
We present the discovery of TOI-6303b and TOI-6330b, two massive transiting super-Jupiters orbiting a M0 and a M2 star respectively, as part of the Searching for GEMS survey. These…
Origins of Super Jupiters: TOI-2145b Has a Moderately Eccentric and Nearly Aligned Orbit
Jiayin Dong, Ashley Chontos, George Zhou +15
Super Jupiters are giant planets with several Jupiter masses. It remains an open question whether these planets originate with such high masses or grow through collisions. Previous…
Gaia-4b and 5b: Radial Velocity Confirmation of Gaia Astrometric Orbital Solutions Reveal a Massive Planet and a Brown Dwarf Orbiting Low-mass Stars
Gudmundur Stefansson, Suvrath Mahadevan, Joshua Winn +31
Gaia astrometry of nearby stars is precise enough to detect the tiny displacements induced by substellar companions, but radial velocity data are needed for definitive confirmation…
Multi-Observatory Research of Young Stellar Energetic Flares (MORYSEF): X-ray Flare Related Phenomena and Multi-epoch Behavior
Konstantin V. Getman, Eric D. Feigelson, Abygail R. Waggoner +8
The most powerful stellar flares driven by magnetic energy occur during the early pre-main sequence (PMS) phase. The Orion Nebula represents the nearest region populated by young s…
Searching for GEMS: TOI-6383Ab, a giant planet transiting an M3-dwarf star in a binary system
Lia Marta Bernabò, Shubham Kanodia, Caleb I. Canas +22
We report on the discovery of a transiting giant planet around the 3500 K M3-dwarf star TOI-6383A located 172 pc from Earth. It was detected by the Transiting Exoplanet Survey Sate…
