Effects of Radiation in Accretion Regions of Classical T Tauri Stars: Pre-heating of accretion column in non-LTE regime
Salvatore Colombo, Laurent Ibgui, Salvatore Orlando +8
Models and observations indicate that the impact of matter accreting onto the surface of young stars produces regions at the base of accretion columns, in which optically thin and…
Non-LTE radiation hydrodynamics in PLUTO
Salvatore Colombo, Laurent Ibgui, Salvatore Orlando +5
Modeling the dynamics of most astrophysical structures requires an adequate description of the radiation-matter interaction. Several numerical (magneto)hydrodynamics codes were upg…
A new view of the corona of classical T Tauri stars: Effects of flaring activity in circumstellar disks
Salvatore Colombo, Salvatore Orlando, Giovanni Peres +5
Classical T Tauri stars (CTTSs) are young low-mass stellar objects accreting mass from their circumstellar disks. They are characterized by high levels of coronal activity as revea…
Origin of the wide-angle hot H2 in DG Tauri: New insight from SINFONI spectro-imaging
Vanessa Agra-Amboage, S. Cabrit, C. Dougados +3
We wish to test the origins proposed for the extended hot H2 at 2000K around the atomic jet from the T Tauri star DGTau, in order to constrain the wide-angle wind structure and the…
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…
YSO accretion shocks: magnetic, chromospheric or stochastic flow effects can suppress fluctuations of X-ray emission
T. Matsakos, J. -P. Chièze, C. Stehlé +9
Context. Theoretical arguments and numerical simulations of radiative shocks produced by the impact of the accreting gas onto young stars predict quasi-periodic oscillations in the…
