The RCB star V854 Cen is surrounded by a hot dusty shell
Olivier Chesneau, Florentin Millour, Orsola De Marco +5
Aims : The hydrogen-deficient supergiants known as R Coronae Borealis (RCB) stars might be the result of a double-degenerate merger of two white dwarfs (WDs), or a final helium she…
Binarity of the LBV HR Car
Th. Rivinius, H. M. J. Boffin, W. J. de Wit +4
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 di…
AMBER/VLTI Snapshot Survey on Circumstellar Environments
Th. Rivinius, W. J. de Wit, Z. Demers +2
OHANA is an interferometric snapshot survey of the gaseous circumstellar environments of hot stars, carried out by the VLTI group at the Paranal observatory. It aims to characteriz…
VLTI status update: a decade of operations and beyond
Antoine Merand, Roberto Abuter, Emmanuel Aller-Carpentier +44
We present the latest update of the European Southern Observatory's Very Large Telescope interferometer (VLTI). The operations of VLTI have greatly improved in the past years: redu…
Dusty Blue Supergiants: News from High-Angular Resolution Observations
Willem-Jan de Wit, Rene Oudmaijer, Jorick Vink
An overview is presented of the recent advances in understanding the B[e] phenomenon among blue supergiant stars in light of high-angular resolution observations and with an emphas…
Near-Infrared Evidence for a Sudden Temperature Increase in Eta Carinae
Andrea Mehner, Kazunori Ishibashi, Patricia Whitelock +4
Aims. Eta Car's ultra-violet, optical, and X-ray light curves and its spectrum suggest a physical change in its stellar wind over the last decade. It was proposed that the mass-los…
