On average properties of inhomogeneous fluids in general relativity III: general fluid cosmologies
Thomas Buchert, Pierre Mourier, Xavier Roy
We investigate effective equations governing the volume expansion of spatially averaged portions of inhomogeneous cosmologies in spacetimes filled with an arbitrary fluid. This wor…
The Acceleration of Superrotation in Simulated Hot Jupiter Atmospheres
Florian Debras, Nathan Mayne, Isabelle Baraffe +5
Context. Atmospheric superrotating flows at the equator are an almost ubiquitous result of simulations of hot Jupiters, and a theory explaining how this zonally coherent flow reach…
On the covariance of scalar averaging and backreaction in relativistic inhomogeneous cosmology
Asta Heinesen, Pierre Mourier, Thomas Buchert
We introduce a generalization of the 4-dimensional averaging window function of Gasperini, Marozzi and Veneziano (2010) that may prove useful for a number of applications. The cova…
Lagrangian theory of structure formation in relativistic cosmology. V. Irrotational fluids
Yong-Zhuang Li, Pierre Mourier, Thomas Buchert +1
We extend the general relativistic Lagrangian perturbation theory, recently developed for the formation of cosmic structures in a dust continuum, to the case of model universes con…
Cosmological backreaction and its dependence on spacetime foliation
Thomas Buchert, Pierre Mourier, Xavier Roy
The subject of cosmological backreaction in General Relativity is often approached by coordinate-dependent and metric-based analyses. We present in this letter an averaging formali…
Fingering convection and cloudless models for cool brown dwarf atmospheres
P. Tremblin, D. S. Amundsen, P. Mourier +5
This work aims to improve the current understanding of the atmospheres of brown dwarfs, especially cold ones with spectral type T and Y, whose modeling is a current challenge. Sili…
