New insight on Young Stellar Objects accretion shocks -- a claim for NLTE opacities
Lionel de Sá, Jean-Pierre Chièze, Chantal Stehlé +3
Context. Accreted material onto CTTSs is expected to form a hot quasi-periodic plasma structure that radiates in X-rays. Simulations of this phenomenon only partly match with obser…
Young stellar object jet models: From theory to synthetic observations
O. Tesileanu, T. Matsakos, S. Massaglia +9
Astronomical observations, analytical solutions and numerical simulations have provided the building blocks to formulate the current theory of young stellar object jets. Although e…
Radiative accretion shocks along nonuniform stellar magnetic fields in classical T Tauri stars
S. Orlando, R. Bonito, C. Argiroffi +9
(abridged) AIMS. We investigate the dynamics and stability of post-shock plasma streaming along nonuniform stellar magnetic fields at the impact region of accretion columns. We stu…
Deflagration to detonation transition by amplification of acoustic waves in type Ia supernovae
Camille Charignon, Jean-Pierre Chièze
We study a new mechanism for deflagration to detonation transition in thermonuclear supernovae (SNe Ia), based on the formation of shocks by amplification of sound waves in the ste…
The dynamical influence of cooling in the envelope of prestellar and protostellar cores
P. Lesaffre, A. Belloche, J. -P. Chieze +1
We compute numerical simulations of spherical collapse triggered by a slow increase in external pressure. We compare isothermal models to models including cooling with a simple but…
Temporal evolution of magnetic molecular shocks II. Analytics of the steady state and semi-analytical construction of intermediate ages
P. Lesaffre, J. -P. Chièze, S. Cabrit +1
In the first paper of this series (Paper I) we computed time dependent simulations of multifluid shocks with chemistry and a transverse magnetic field frozen in the ions, using an…
