The wind and the magnetospheric accretion onto the T Tauri star S Coronae Australis at sub-au resolution
R. Garcia Lopez, K. Perraut, A. Caratti o Garatti +70
To investigate the inner regions of protoplanetary disks, we performed near-infrared interferometric observations of the classical TTauri binary system S CrA. We present the first…
Twelve years of spectroscopic monitoring in the Galactic Center: the closest look at S-stars near the black hole
M. Habibi, S. Gillessen, F. Martins +11
We study the young S-stars within a distance of 0.04 pc from the supermassive black hole in the center of our Galaxy. Given how inhospitable the region is for star formation, their…
3D AMR hydrosimulations of a compact source scenario for the Galactic Centre cloud G2
A. Ballone, M. Schartmann, A. Burkert +8
The nature of the gaseous and dusty cloud G2 in the Galactic Centre is still under debate. We present three-dimensional hydrodynamical adaptive mesh refinement (AMR) simulations of…
Accretion-ejection morphology of the microquasar SS433 resolved at sub-au scale
GRAVITY Collaboration, P. -O. Petrucci, I. Waisberg +67
We present the first optical observation at sub-milliarcsecond (mas) scale of the microquasar SS 433 obtained with the GRAVITY instrument on the VLT interferometer. The 3.5 hour ex…
First Light for GRAVITY: Phase Referencing Optical Interferometry for the Very Large Telescope Interferometer
GRAVITY Collaboration, R. Abuter, M. Accardo +130
GRAVITY is a new instrument to coherently combine the light of the European Southern Observatory Very Large Telescope Interferometer to form a telescope with an equivalent 130 m di…
Probing the Gas Density in our Galactic Center: Moving Mesh Simulations of G2
Elad Steinberg, Re'em Sari, Orly Gnat +11
The G2 object has recently passed its pericenter passage in our Galactic Center. While the emission shows clear signs of tidal interaction, the change in the observed lumino…
