VLTI-AMBER velocity-resolved aperture-synthesis imaging of Eta Carinae with a spectral resolution of 12000. Studies of the primary star wind and innermost wind-wind collision
G. Weigelt, K. -H. Hofmann, D. Schertl +26
Context. The mass loss from massive stars is not understood well. Eta Car is a unique object for studying the massive stellar wind during the LBV phase. It is also an eccentric bin…
Luminous blue variables: An imaging perspective on their binarity and near environment
Christophe Martayan, Alex Lobel, Dietrich Baade +18
Context. Luminous blue variables (LBVs) are rare massive stars with very high luminosity. They are characterized by strong photo-metric and spectroscopic variability related to tra…
Direct imaging with a hypertelescope of red supergiant stellar surfaces
Fabien Patru, Andrea Chiavassa, Denis Mourard +1
High angular resolution images obtained with a hypertelescope can strongly constrain the radiative-hydrodynamics simulations of red supergiant (RSG) stars, in terms of intensity co…
X-shooter, NACO, and AMBER observations of the LBV Pistol Star \footnote{Based on ESO runs 85.D-0182A, 085.D-0625AC}
Christophe Martayan, Ronny Blomme, Jean-Baptiste Le Bouquin +15
We present multi-instruments and multi-wavelengths observations of the famous LBV star Pistol Star. These observations are part of a larger program about early O stars at different…
High-angular resolution observations of the Pistol Star
Christophe Martayan, Ronny Blomme, Jean-Baptiste Le Bouquin +15
First results of near-IR adaptive optics (AO)-assisted imaging, interferometry, and spectroscopy of this Luminous Blue Variable (LBV) are presented. They suggest that the Pistol St…
