Investigating three Sirius-like systems with SPHERE
R. Gratton, V. D'Orazi, T. A. Pacheco +61
Sirius-like systems are wide binaries composed of a white dwarf (WD) and a companion of a spectral type earlier than M0. The WD progenitor evolves in isolation, but its wind during…
A triple star in disarray -- Multi-epoch observations of T Tauri with VLT-SPHERE and LBT-LUCI
M. Kasper, K. K. R. Santhakumari, T. M. Herbst +24
T Tauri remains an enigmatic triple star for which neither the evolutionary state of the stars themselves, nor the geometry of the complex outflow system is completely understood.…
Interpreting high spatial resolution line observations of planet-forming disks with gaps and rings -- The case of HD 163296
Ch. Rab, I. Kamp, C. Dominik +5
Spatially resolved continuum observations of planet-forming disks show prominent ring and gap structures in their dust distribution. However, the picture from gas observations is m…
Disk Evolution Study Through Imaging of Nearby Young Stars (DESTINYS): A close low mass companion to ET Cha
C. Ginski, F. Ménard, Ch. Rab +25
To understand the formation of planetary systems, one needs to understand the initial conditions of planet formation, i.e. the young gas-rich planet forming disks. Spatially resolv…
The circumstellar environment of EX Lup: the SPHERE and SINFONI views
E. Rigliaco, R. Gratton, A. Kospal +15
EX Lup is a well-studied T Tauri star that represents the prototype of young eruptive stars EXors. In this paper we analyze new adaptive optics imaging and spectroscopic observatio…
Gap, shadows, spirals, streamers: SPHERE observations of binary-disk interactions in GG Tau A
M. Keppler, A. Penzlin, M. Benisty +31
A large fraction of stars is found to be part of binary or higher-order multiple systems. The ubiquity of planets found around single stars raises the question if and how planets i…
