A transiting giant planet in orbit around a 0.2-solar-mass host star
Edward M. Bryant, Andrés Jordán, Joel D. Hartman +56
Planet formation models suggest that the formation of giant planets is significantly harder around low-mass stars, due to the scaling of protoplanetary disc masses with stellar mas…
Transiting Exoplanets with JWST
S. Seager, D. Deming, J. A. Valenti
The era of exoplanet characterization is upon us. For a subset of exoplanets -- the transiting planets -- physical properties can be measured, including mass, radius, and atmospher…
TOI-3884 b: A rare 6-R planet that transits a low-mass star with a giant and likely polar spot
J. M. Almenara, X. Bonfils, T. Forveille +19
The Transiting Exoplanet Survey Satellite mission identified a deep and asymmetric transit-like signal with a periodicity of 4.5 days orbiting the M4 dwarf star TOI-3884. The signa…
TOI-6508b: A massive transiting brown dwarf orbiting a low-mass star
K. Barkaoui, D. Sebastian, S. Zúñiga-Fernández +44
We report the discovery of a transiting brown dwarf orbiting a low-mass star, TOI-6508b. Today, only ~50 transiting brown dwarfs have been discovered. TOI-6508b was first detected…
On the Method to Infer an Atmosphere on a Tidally-Locked Super Earth Exoplanet and Upper limits to GJ 876d
S. Seager, D. Deming
We develop a method to infer or rule out the presence of an atmosphere on a tidally-locked hot super Earth. The question of atmosphere retention is a fundamental one, especially fo…
Clouds and Chemistry: Ultracool Dwarf Atmospheric Properties from Optical and Infrared Colors
M. S. Marley, S. Seager, D. Saumon +4
The optical and infrared colors of L and T dwarfs are sensitive to cloud sedimentation and chemical equilibrium processes in their atmospheres. The i'-z' vs. J-K color-color diagra…
