Multiple Star Systems in the Orion Nebula
GRAVITY collaboration, Martina Karl, Oliver Pfuhl +133
This work presents an interferometric study of the massive-binary fraction in the Orion Trapezium Cluster with the recently comissioned GRAVITY instrument. We observe a total of 16…
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…
Resolved astrometric orbits of ten O-type binaries
J. -B. Le Bouquin, H. Sana, E. Gosset +11
Our long term aim is to derive model-independent stellar masses and distances for long period massive binaries by combining apparent astrometric orbit with double-lined radial velo…
The LBV HR Car has a partner: Discovery of a companion with the VLTI
Henri M. J. Boffin, Thomas Rivinius, Antoine Merand +6
Luminous Blue Variables (LBVs) are massive stars caught in a post-main sequence phase, during which they are losing a significant amount of mass. As, on one hand, it is thought tha…
Masses of the components of SB2 binaries observed with Gaia. II. Masses derived from PIONIER interferometric observations for Gaia validation
J. -L. Halbwachs, H. M. J. Boffin, J. -B. Le Bouquin +15
In anticipation of the Gaia astrometric mission, a sample of spectroscopic binaries is being observed since 2010 with the Sophie spectrograph at the Haute--Provence Observatory. Ou…
Young Stellar Object Variability (YSOVAR): Long Timescale Variations in the Mid-Infrared
L. M. Rebull, A. M. Cody, K. R. Covey +32
The YSOVAR (Young Stellar Object VARiability) Spitzer Space Telescope observing program obtained the first extensive mid-infrared (3.6 & 4.5 um) time-series photometry of the Orion…
