X-Shooting ULLYSES: massive stars at low metallicity. I. Project Description
Jorick S. Vink, A. Mehner, P. A. Crowther +78
Observations of individual massive stars, super-luminous supernovae, gamma-ray bursts, and gravitational-wave events involving spectacular black-hole mergers, indicate that the low…
Stellar variability in Gaia DR3. I. Three-band photometric dispersions for 145 million sources
J. Maíz Apellániz, G. Holgado, M. Pantaleoni González +1
CONTEXT: The unparalleled characteristics of Gaia photometry make it an excellent choice to study stellar variability. AIMS: To measure the phot. dispersion in G+G_BP+G_RP of the 1…
The IACOB project VIII. Searching for empirical signatures of binarity in fast-rotating O-type stars
N. Britavskiy, S. Simón-Díaz, G. Holgado +6
The empirical distribution of projected rotational velocities (vsini) in massive O-type stars is characterized by a dominant slow velocity component and a tail of fast rotators. Bi…
Gaia-ESO Survey: massive stars in the Carina Nebula. A new census of OB stars
S. R. Berlanas, J. Maíz Apellániz, A. Herrero +16
The Gaia-ESO survey sample of massive OB stars in the Carina Nebula consists of 234 stars. The addition of brighter sources from the Galactic O-Star Spectroscopic Survey and additi…
