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.…
A High Angular Resolution Survey of Massive Stars in Cygnus OB2: Adaptive Optics Results from the Gemini Near-InfraRed Imager
S. M. Caballero-Nieves, D. R. Gies, E. K. Baines +8
We present results of a high angular resolution survey of massive OB stars in the Cygnus OB2 association that we conducted with the NIRI camera and ALTAIR adaptive optics system of…
Investigating the nature of the extended structure around the Herbig star RCrA using integral field and high-resolution spectroscopy
E. Rigliaco, R. Gratton, D. Mesa +24
We present a detailed analysis of the extended structure detected around the young and close-by Herbig Ae/Be star RCrA. This is a young triple system with an intermediate mass cent…
The SPHERE view of the jet and the envelope of RY Tau
A. Garufi, L. Podio, F. Bacciotti +40
Jets are rarely associated with pre-main-sequence intermediate-mass stars. Optical and near-IR observations of jet-driving sources are often hindered by the presence of a natal env…
ISPY - the NaCo Imaging Survey for Planets around Young stars: A young companion candidate embedded in the R CrA cloud
G. Cugno, S. P. Quanz, R. Launhardt +13
Within the NaCo-ISPY exoplanet imaging program, we aim at detecting and characterizing the population of low-mass companions at wide separations (10AU), focusing in partic…
