Multi-epoch VLTI-PIONIER imaging of the supergiant V766 Cen: Image of the close companion in front of the primary

M. Wittkowski, F. J. Abellan, B. Arroyo-Torres +10

The star V766 Cen (=HR 5171A) was originally classified as a yellow hypergiant but lately found to more likely be a 27-36 Msun red supergiant (RSG). Recent observations indicated a…

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…

GRAVITY spectro-interferometric study of the massive multiple stellar system HD 93 206 A

J. Sanchez-Bermudez, A. Alberdi, R. Barba +9

Characterization of the dynamics of massive star systems and the astrophysical properties of the interacting components are a prerequisite for understanding their formation and evo…

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…

Sub-milliarcsecond Optical Interferometry of the HMXB BP Cru with VLTI/GRAVITY

GRAVITY Collaboration, I. Waisberg, J. Dexter +68

We observe the HMXB BP Cru using interferometry in the near-infrared K band with VLTI/GRAVITY. Continuum visibilities are at most partially resolved, consistent with the predicted…

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…
