Journal ArticleDOI
Cloudless atmospheres for L/T dwarfs and extra-solar giant planets
Pascal Tremblin,David S. Amundsen,Gilles Chabrier,Isabelle Baraffe,Benjamin Drummond,Sasha Hinkley,Pierre Mourier,O. Venot +7 more
TL;DR: In this paper, the authors proposed a new, completely different explanation for BD and extrasolar giant planet (EGP) spectral evolution, without the need to invoke clouds, and showed that due to the slowness of the CO/CH4 and N2/NH3 chemical reactions, brown dwarf (L and T, respectively) and EGP atmospheres are subject to a thermo-chemical instability similar in nature to the fingering or chemical convective instability present in Earth oceans and at the Earth core/mantle boundary.
Journal ArticleDOI
A library of ATMO forward model transmission spectra for hot Jupiter exoplanets
Jayesh M. Goyal,Nathan J. Mayne,David K. Sing,Benjamin Drummond,Pascal Tremblin,David S. Amundsen,David S. Amundsen,Thomas M. Evans,Aarynn L. Carter,Jessica Spake,Isabelle Baraffe,Nikolay Nikolov,James Manners,James Manners,Gilles Chabrier,Gilles Chabrier,Eric Hébrard +16 more
TL;DR: In this paper, a grid of forward model transmission spectra, adopting an isothermal temperature-pressure profile, along with corresponding equilibrium chemical abundances for 117 observationally significant hot exoplanets (equilibrium temperatures of 547-2710 K), is presented.
Journal ArticleDOI
The Mass-Dependence of Angular Momentum Evolution in Sun-Like Stars
Sean P. Matt,A. Sacha Brun,Isabelle Baraffe,Isabelle Baraffe,Jerome Bouvier,Jerome Bouvier,Gilles Chabrier +6 more
TL;DR: In this paper, a physically motivated scaling for the dependence of stellar-wind torque on Rossby number was derived to better understand the observed distributions of rotation rate and magnetic activity of sun-like and low-mass stars.
Journal ArticleDOI
1RXS J232953.9+062814: A Dwarf Nova with a 64 Minute Orbital Period and a Conspicuous Secondary Star
John R. Thorstensen,William H. Fenton,Joseph Patterson,Jonathan Kemp,Thomas Krajci,Isabelle Baraffe +5 more
TL;DR: In this article, the authors present spectroscopy and time series photometry of the newly discovered dwarf nova 1RXS J232953, which reveals a superhump with a period of 66.06(6) minutes.
