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…
An Aligned Very-Low-Mass Star Orbiting an M dwarf and Obliquity Patterns Across Giant Planets, Brown Dwarfs, and Binary Stars
Tianjun Gan, Alexandrine L'Heureux, Étienne Artigau +4
Stellar obliquity serves as a key diagnostic for tracing the dynamical evolution of bound systems-from giant planets and brown dwarfs to stellar binaries-revealing whether these di…
Revisiting the atmosphere of HAT-P-70b with CARMENES high-resolution transmission spectroscopy
Tianjun Gan, Jaume Orell-Miquel, Fei Yan +19
Owing to hot and inflated envelopes that facilitate atmospheric studies, ultra-hot Jupiters (UHJs) have attracted much attention. Significant progress has been achieved, from enlar…
Dynamical Instability of Multi-planet Systems and Free-floating Planets
Ruocheng Zhai, Man Hoi Lee, Tianjun Gan +1
The ejection of planets by the instability of planetary systems is a potential source of free-floating planets. We numerically simulate multi-planet systems to study the evolution…
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…
Metallicity Dependence of Giant Planets around M Dwarfs
Tianjun Gan, Christopher A. Theissen, Sharon X. Wang +2
We investigate the stellar metallicity ([Fe/H] and [M/H]) dependence of giant planets around M dwarfs by comparing the metallicity distribution of 746 field M dwarfs without known…
