Abstract VLTI/AMBER and VLTI/PIONIER observations of the LBV HR Car show an interferometric signature that could not possibly be explained by an extended wind, more or less symmetrically distributed around a single object. Instead, observations both in the Brγ line and the H-band continuum are best explained by two point sources (or alternatively one point source and one slightly extended source) at about 2 mas separation and a contrast ratio of about 1:5. These observations establish that HR…

Imaging and Spectroscopy of The Massive Binaries MWC 314 and HD 168625
VLT-NACO imaging and spectroscopic monitoring of MWC 314 shows it is a hierarchical triple system consisting of a close massive binary that contains a Luminous Blue Variable (LBV), and a third
Luminous blue variables: An imaging perspective on their binarity and near environment
Luminous blue variables (LBVs) are rare massive stars with very high luminosity. They are characterized by strong photo-metric and spectroscopic variability related to transient eruptions. The

The study of binary stars is critical to apprehend many of the most interesting classes of stars. Moreover, quite often, the study of stars in binary systems is our only mean to constrain stellar

Modelling the asymmetric wind of the luminous blue variable binary MWC 314
Aims. We present a spectroscopic analysis of MWC 314, a luminous blue variable (LBV) candidate with an extended bipolar nebula. The detailed spectroscopic variability is investigated to determine if
Binary Interaction Dominates the Evolution of Massive Stars
More than 70% of all massive stars will exchange mass with a companion, leading to a binary merger in one-third of the cases, greatly exceed previous estimates and imply that binary interaction dominates the evolution of massive stars, with implications for populations ofmassive stars and their supernovae.
