Journal ArticleDOI
The unified model, a fully-compressible, non-hydrostatic, deep atmosphere global circulation model, applied to hot Jupiters - ENDGame for a HD 209458b test case
Nathan J. Mayne,Isabelle Baraffe,David M. Acreman,Chris Smith,Matthew K. Browning,David S. Amundsen,Nigel Wood,John Thuburn,David Jackson +8 more
TL;DR: In this paper, the authors demonstrate the successful adaptation of the most sophisticated dynamical core, the component of the GCM which solves the equations of motion for the atmosphere, available within the EndGame (Even Newer Dynamics for General atmospheric modelling of the environment).
Journal ArticleDOI
The Effect of Magnetic Activity on Low-Mass Stars in Eclipsing Binaries
Juan Carlos Morales,José Gallardo,Ignasi Ribas,Carme Jordi,Isabelle Baraffe,Isabelle Baraffe,Gilles Chabrier +6 more
TL;DR: In this paper, the effect of magnetic activity both on models and on the observational analysis of eclipsing binary systems using a sample of such systems with accurate fundamental properties was tested, and it was shown that unrealistically high spot coverages need to be assumed to reproduce the observations.
Journal ArticleDOI
Cloudless Atmospheres for L/T Dwarfs and Extrasolar Giant Planets
Pascal Tremblin,Pascal Tremblin,David S. Amundsen,David S. Amundsen,David S. Amundsen,Gilles Chabrier,Gilles Chabrier,Isabelle Baraffe,Isabelle Baraffe,Benjamin Drummond,Sasha Hinkley,Pierre Mourier,Pierre Mourier,Olivia Venot +13 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 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
Observed Luminosity Spread in Young Clusters and FU Ori Stars: A Unified Picture
TL;DR: In this article, the authors present a global scenario based on calculations coupling episodic accretion histories derived from numerical simulations of collapsing cloud prestellar cores of various masses and subsequent protostar evolution.
Journal ArticleDOI
Accuracy tests of radiation schemes used in hot Jupiter global circulation models
David S. Amundsen,Isabelle Baraffe,Pascal Tremblin,James Manners,Wolfgang Hayek,Nathan J. Mayne,David M. Acreman +6 more
TL;DR: In this article, the authors adapted the UK Met Office GCM, the Unified Model (UM), for the study of hot Jupiters, and presented the adaptation of the Edwards-Slingo radiation scheme based on the two-stream approximation and the correlated-k method.
