Mapping Wolf-Rayet winds with spectro-interferometry I. Detection of multiple co-rotating interaction regions in WR 6
K. Deshmukh, A. -N. Chené, A. J. Frost +8
WR 6 is the prototype for periodic variability due to large-scale wind structures in Wolf-Rayet (WR) stars, showing a consistent periodicity of 3.76 d in photometry, spectroscopy,…
Toward 3D orbits of wide sdO/B binaries I. Six composite systems spatially resolved with VLTI/GRAVITY
K. Deshmukh, S. Geier, H. Sana +7
Hot subdwarf stars (sdO/Bs) are widely considered to be products of binary evolution. A significant fraction of them are found in long-period or wide binaries ( d) with main…
ESO User Support and Observation Preparation for VLTI Science Operations
M. Wittkowski, G. Beccari, A. Corporaal +15
We present recent enhancements to VLTI observing capabilities from a user-oriented perspective, together with new developments in ESO's Observation Handling Tools and end-to-end op…
Southern massive stars at high angular resolution: WR 25 is a massive hierarchical triple system
K. Deshmukh, L. Mahy, H. Sana +6
WR 25 is a massive colliding-wind binary in the Carina nebula comprising a WN6ha primary with an O5 companion in an eccentric 208-d orbit. Recent spectroscopic analysis estimates t…
Southern Massive Stars at High Angular Resolution (SMaSH+): Properties of hierarchical massive triples
E. Bordier, H. Sana, A. J. Frost +9
While massive stars are frequently found in triple architectures, the lack of observed parameter distributions has long remained a bottleneck for statistical models of their evolut…
Interferometry of Massive Stars: Multiplicity, Magnetism, and Stellar Winds
H. Sana E. Bordier, K. Deshmukh, A. J. Frost +7
After decades of efforts, optical long-baseline interferometry has become a mainstream observational technique in terms of operation robustness and user friendliness. Interferometr…
An interferometric study of B star multiplicity
A. J. Frost, H. Sana, J-B Le Bouquin +7
Massive stars can have extreme effects on their environments from local to galactic scales. While O star multiplicity has been studied over a broad separation range (to the point w…
The highly magnetic Wolf-Rayet binary HD 45166 resolved with VLTI/GRAVITY
K. Deshmukh, T. Shenar, A. Mérand +9
HD 45166 was recently reported to be a long-period binary comprising a B7V star and a highly magnetic (kG) hot Wolf-Rayet-like component, dubbed a…
VLTI/GRAVITY enables the determination of the first dynamical masses of a classical Be + stripped and bloated pre-subdwarf binary
R. Klement, Th. Rivinius, D. Baade +7
HR~6819 is the first post-mass transfer binary system composed of a classical Be star and a bloated pre-subdwarf stripped star directly confirmed by interferometry. While the Be st…
Investigating 39 Galactic Wolf-Rayet stars with VLTI/GRAVITY: Uncovering A Long Period Binary Desert
K. Deshmukh, H. Sana, A. Mérand +16
Wolf-Rayet stars (WRs) are one of the final evolutionary stages of massive stars and immediate progenitors of stellar-mass black holes. Their multiplicity forms an important anchor…
Unveiling accretion in the massive YSO G033.3891. Spatial and kinematic constraints from the CO bandhead emission
E. Koumpia, D. Sun, M. Koutoulaki +4
The inner parts of the hot discs surrounding massive young stellar objects (MYSOs) are still barely explored due to observational limitations in terms of angular resolution, scarci…
Gaia uncovers difference in B and Be star binarity at small scales: evidence for mass transfer causing the Be phenomenon
Jonathan M. Dodd, René D. Oudmaijer, Isaac C. Radley +2
Be stars make up almost 20% of the B star population, and are rapidly rotating stars surrounded by a disc; however the origin of this rotation remains unclear. Mass transfer within…
