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…

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…
