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…
Collapse of turbulent massive cores with ambipolar diffusion and hybrid radiative transfer I. Accretion and multiplicity
R. Mignon-Risse, M. González, B. Commerçon +1
(Abridged) Context. Massive stars form in magnetized and turbulent environments, and are often located in stellar clusters. Their accretion mechanism, as well as the origin of thei…
Empirical determination of atomic line parameters of the 1.5 m spectral region
J. C. Trelles Arjona, B. Ruiz Cobo, M. J. Martínez González
Both the quality and amount of astrophysical data are steadily increasing over time owing to the improvement of telescopes and their instruments. This requires corresponding evolut…
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…
A statistical analysis of dust polarization properties in ALMA observations of Class 0 protostellar cores
V. J. M. Le Gouellec, A. J. Maury, V. Guillet +8
Recent observational progress has challenged the dust grain-alignment theories used to explain the polarized dust emission routinely observed in star-forming cores. In an effort to…
Photospheric magnetic topology of a north polar region
A. Pastor Yabar, M. J. Martínez González, M. Collados
Aims. We aim to characterise the magnetism of a large fraction of the north polar region close to a maximum of activity, when the polar regions are reversing their dominant polarit…
Inference of magnetic fields in the very quiet Sun
M. J. Mart\' inez González, A. Pastor Yabar, A. Lagg +29
We present high-precision spectro-polarimetric data with high spatial resolution (0.4) of the very quiet Sun at 1.56m obtained with the GREGOR telescope to shed some light o…
Magnetic topology of the north solar pole
A. Pastor Yabar, M. J. Martínez González, M. Collados
We study the polar magnetism near an activity maximum when these regions change their polarity, from which it is expected that its magnetism should be less affected by the global f…
Probing deep photospheric layers of the quiet Sun with high magnetic sensitivity
A. Lagg, S. K. Solanki, H. -P. Doerr +31
Context. Investigations of the magnetism of the quiet Sun are hindered by extremely weak polarization signals in Fraunhofer spectral lines. Photon noise, straylight, and the system…
Active region filaments might harbor weak magnetic fields
C. J. Díaz Baso, M. J. Martínez González, A. Asensio Ramos
Recent spectropolarimetric observations of active region filaments have revealed polarization profiles with signatures typical of the strong field Zeeman regime. The conspicuous ab…
Radiation Magnetohydrodynamics In Global Simulations Of Protoplanetary Disks
M. Flock, S. Fromang, M. González +1
Our aim is to study the thermal and dynamical evolution of protoplanetary disks in global simulations, including the physics of radiation transfer and magneto-hydrodynamic (MHD) tu…
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…
