Atmospheric Diversity of Giant Planet Analogs from 3-5um with SPHEREx
Rocio Kiman, Brendan P. Bowler, Jerry W. Xuan +2
The emergent spectra of giant planets peak at thermal infrared wavelengths (3-5um) and possess atmospheric features in this regime that trace carbon chemistry, vertical mixing, clo…
Pushing the Limit of Asteroseismic Detection for Cool Dwarfs using TESS and Deep Learning
Waly M Z Karim, Rocio Kiman, Derek Buzasi +6
Asteroseismology provides a powerful probe of stellar interiors by detecting stellar oscillations, including solar-like oscillations, which are stochastically excited by near-surfa…
Gaia Exoplanet Orbits, Demographics, and Evolution Survey (GEODES): Characteristics of Three Long-Period Companions Accelerating their Host Stars
Judah Van Zandt, Brendan Bowler, Erik Petigura +12
The upcoming release of DR4 will yield thousands of giant planet candidates, eventually enabling studies of giant planet eccentricities, masses, and occurrence rates across…
An Outer Giant Planet or Brown Dwarf in the 51 Pegasi System?
Marvin Morgan, Brendan P. Bowler, Kyle Franson +15
51 Pegasi harbors the first confirmed extrasolar planet orbiting a Sun-like star. Decades of continued radial velocity (RV) observations have since uncovered signatures of an addit…
Tidally Heated Sub-Neptunes, Refined Planetary Compositions, and Confirmation of a Third Planet in the TOI-1266 System
Michael Greklek-McKeon, Shreyas Vissapragada, Heather A. Knutson +38
TOI-1266 is a benchmark system of two temperate ( 450 K) sub-Neptune-sized planets orbiting a nearby M dwarf exhibiting a rare inverted architecture with a larger interior plane…
