Large-scale environments of binary AGB stars probed by Herschel. II: Two companions interacting with the wind of pi1 Gruis
A. Mayer, A. Jorissen, C. Paladini +12
Context. The Mass loss of Evolved StarS (MESS) sample observed with PACS on board the Herschel Space Observatory revealed that several asymptotic giant branch (AGB) stars are surro…
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…
V838 Monocerotis: the central star and its environment a decade after outburst
Olivier Chesneau, Florentin Millour, Orsola De Marco +8
Aims. V838 Monocerotis erupted in 2002, brightened in a series of outbursts, and eventually developed a spectacular light echo. A very red star emerged a few months after the outbu…
Cheapest nuller in the world: Crossed beamsplitter cubes
F. Henault, A. Spang
In this communication is described a new type of Achromatic phase shifter (APS) suitable for both nulling interferometry and coronagraphy, based on a couple of crossed beamsplitter…
The variable stellar wind of Rigel probed at high spatial and spectral resolution
O. Chesneau, A. Kaufer, O. Stahl +5
We present a spatially resolved, high-spectral resolution (R=12000) K-band temporal monitoring of Rigel using AMBER at the VLTI. Rigel was observed in the Bracket Gamma line and it…
The yellow hypergiant HR 5171 A: Resolving a massive interacting binary in the common envelope phase
O. Chesneau, A. Meilland, E. Chapellier +20
We initiated long-term optical interferometry monitoring of the diameters of unstable yellow hypergiants (YHG) with the goal of detecting both the long-term evolution of their radi…
