Stellar Multiplicity of M Dwarfs with Short-period Giant Planets, and the Characterization of TOI-5628Ab
Tianjun Gan, Alexandrine L'Heureux, Charles Cadieux +33
Binary stars are ubiquitous, yet it remains unclear how wide-orbit stellar companions influence the formation of hot Jupiters, particularly around M dwarfs. Here, we first report t…
RV and TTV Measurements of Two Transiting Long-Period Giants around TOI-4600
Tong Hu, Zitao Lin, Sharon X. Wang +27
TOI-4600b and c, originally identified by the Transiting Exoplanet Survey Satellite (TESS) and reported by I. Mireles et al. (2023), are a rare pair of transiting long-period giant…
HD 164604 c: a second giant planet on a 15-yr orbit and the constraint of the planet-planet mutual inclination
Guang-Yao Xiao, Fabo Feng, R. Paul Butler +4
We report the discovery of a new massive giant planet, HD 164604 c ( au, and or $7.6_{-1.0}…
TOI-6692b: An eccentric 130 day period giant planet with a single transit from TESS
Allyson Bieryla, Karen A. Collins, George Zhou +46
We report the discovery and characterization of TOI-6692 b, an eccentric (e~0.54) Jupiter on a 130-day orbit. TOI-6692 b was first detected as a community TESS Object of Interest (…
Detection of four cold Jupiters through combined analyses of radial velocity and astrometry data
Yiyun Wu, Guang-Yao Xiao, R. Paul Butler +19
Cold Jupiters play a crucial role in planet formation and dynamical evolution. Since their initial discovery around 47 UMa, they have attracted significant interest, yet their form…
A New Brown Dwarf Orbiting an M star and An Investigation on the Eccentricity Distribution of Transiting Long-Period Brown Dwarfs
Tianjun Gan, Charles Cadieux, Shigeru Ida +32
The orbital eccentricities of brown dwarfs encode valuable information of their formation and evolution history, providing insights into whether they resemble giant planets or stel…
