Pillars and globules at the edges of H ii regions, Confronting Herschel observations and numerical simulations
P. Tremblin, V. Minier, N. Schneider +24
Pillars and globules are present in many high-mass star-forming regions, such as the Eagle nebula (M16) and the Rosette molecular cloud, and understanding their origin will help ch…
Lattice QCD at the physical point meets SU(2) chiral perturbation theory
Stephan Durr, Zoltan Fodor, Christian Hoelbling +9
We perform a detailed, fully-correlated study of the chiral behavior of the pion mass and decay constant, based on 2+1 flavor lattice QCD simulations. These calculations are implem…
Simulations of protostellar collapse using multigroup radiation hydrodynamics. II. The second collapse
N. Vaytet, G. Chabrier, E. Audit +4
Star formation begins with the gravitational collapse of a dense core inside a molecular cloud. As the collapse progresses, the centre of the core begins to heat up as it becomes o…
Simulation of sharp interface multi-material flows involving an arbitrary number of components through an extended five-equation model
Marie Billaud Friess, Samuel Kokh
In this paper, we present an anti-diffusive method dedicated to the simulation of interface flows on Cartesian grids involving an arbitrary number m of compress- ible components. O…
Conservative Regridding When Grid Cell Edges Are Unknown -- Case of SCRIP
Joël Chavas, Édouard Audit, Laure Coquart +1
Nowadays, climate models rely on couplers. Each complete climate model is broken into different sub-models (oceanic, atmospheric,...), each one working on a different grid. The cou…
The influence of frequency-dependent radiative transfer on the structures of radiative shocks
N. Vaytet, M. Gonzalez, E. Audit +1
Radiative shocks are shocks in a gas where the radiative energy and flux coming from the very hot post-shock material are non-negligible in the shock's total energy budget, and are…
