The physics of extrasolar gaseous planets : from theory to observable signatures
, 2004 We review our present understanding of the physical properties of substellar objects, brown dwarfs and irradiated or non-irradiated gaseous exoplanets. This includes a description of their internal properties, mechanical structure and heat content, their atmospheric properties, thermal profile and emergent spectrum, and their evolution, in particular ...Chabrier, Gilles, Allard, France, Baraffe, Isabelle, Barman, T., Hauschildt, P.

The Astronomical Journal, 2023 We report the discovery and orbital characterization of three new transiting warm giant planets. These systems were initially identified as presenting single-transit events in the light curves generated from the full-frame images of the Transiting ...Rafael Brahm, Solène Ulmer-Moll, Melissa J.

The Astrophysical Journal Letters, 2023 The presence of aerosols is intimately linked to the global energy budget and the composition of a planet’s atmosphere. Their ability to reflect incoming light prevents energy from being deposited into the atmosphere, and they shape the spectra of ...Bob Jacobs, Jean-Michel Désert, Peter Gao, Caroline V.

The Astronomical Journal, 2023 We confirm the planetary nature of TOI-5344 b as a transiting giant exoplanet around an M0-dwarf star. TOI-5344 b was discovered with the Transiting Exoplanet Survey Satellite photometry and confirmed with ground-based photometry (the Red Buttes ...Te Han, Paul Robertson, Shubham Kanodia, Caleb Cañas, Andrea S.
