Towards a multigrid method for the M1 model for radiative transfer
Hélène Bloch, Pascal Tremblin, Matthias González +1
We present a geometric multigrid solver for the M1 model of radiative transfer without source terms. In radiative hydrodynamics applications, the radiative transfer needs to be sol…
Radiative Rayleigh-Taylor Instability and the structure of clouds in planetary atmospheres
P. Tremblin, H. Bloch, M. González +5
Clouds are expected to form in a wide range of conditions in the atmosphere of exoplanets given the large range of possible condensible species. However this diversity might lead t…
A high-performance and portable asymptotic preserving radiation hydrodynamics code with the M1 model
H. Bloch, P. Tremblin, M. González +2
Aims. We present a new radiation hydrodynamics code, called "ARK-RT" which uses a two-moment model with the M1 closure relation for radiative transfer. This code aims at being read…
Influence of macroclumping on type II supernova light curves
Luc Dessart, Edouard Audit
Core-collapse supernova (SN) ejecta are probably structured on both small and large scales, with greater deviations from spherical symmetry nearer the explosion site. Here, we pres…
A high performance and portable all-Mach regime flow solver code with well-balanced gravity. Application to compressible convection
T. Padioleau, P. Tremblin, E. Audit +2
Convection is an important physical process in astrophysics well-studied using numerical simulations under the Boussinesq and/or anelastic approximations. However these approaches…
Thermo-compositional diabatic convection in the atmospheres of brown dwarfs and in Earth's atmosphere and oceans
P. Tremblin, T. Padioleau, M. Phillips +12
By generalizing the theory of convection to any type of thermal and compositional source terms (diabatic processes), we show that thermohaline convection in Earth oceans, fingering…
