A relation between the radial velocity dispersion of young clusters and their age: Evidence for hardening as the formation scenario of massive close binaries
M. C. Ramírez-Tannus, F. Backs, A. de Koter +8
The majority of massive stars ( ) in OB associations are found in close binary systems. Nonetheless, the formation mechanism of these close massive binaries is…
The GRAVITY Young Stellar Object survey IV. The CO overtone emission in 51 Oph at sub-au scales
GRAVITY Collaboration, M. Koutoulaki, R. Garcia Lopez +69
51 Oph is a Herbig Ae/Be star that exhibits strong near-infrared CO ro-vibrational emission at 2.3 micron, most likely originating in the innermost regions of a circumstellar disc.…
VLT/X-shooter spectroscopy of massive young stellar objects in the 30 Doradus region of the Large Magellanic Cloud
M. L. van Gelder, L. Kaper, J. Japelj +13
The process of massive star () formation is still poorly understood. Observations of massive young stellar objects (MYSOs) are challenging due to their rarity, shor…
A dearth of short-period massive binaries in the young massive star forming region M17: Evidence for a large orbital separation at birth?
H. Sana, M. Ramirez-Tannus, A. de Koter +3
The formation of massive stars remains poorly understood and little is known about their birth multiplicity properties. Here, we investigate the strikingly low radial-velocity disp…
