The Alma catalogue of OB stars. III. A cross-match with Gaia DR3 and an extension based on new spectral classifications
M. Pantaleoni González, J. Maíz Apellániz, R. H. Barbá +4
We present the third installment of the Alma Luminous Star (ALS) catalogue, aimed at creating the most comprehensive and clean sample of Galactic massive stars. This update extends…
Gaia-ESO Survey: massive stars in the Carina Nebula. II. The spectroscopic analysis of the O-star population
S. R. Berlanas, L. Mahy, A. Herrero +9
The new census of massive stars in the Carina nebula reveals the presence of 54 apparently single O-type stars in the Car OB1 association, an extremely active star-forming region w…
An in-depth analysis of the differentially expanding star cluster Stock 18 (Villafranca O-036) using Gaia DR3 and ground-based data
J. Maíz Apellániz, A. R. Youssef, M. S. El-Nawawy +4
(ABRIDGED) CONTEXT: The Villafranca project is combining Gaia data with ground-based surveys to analyze Galactic stellar groups with OB stars. AIMS: We want to analyze Stock 18 wit…
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…
A search for Galactic runaway stars using Gaia Data Release 1 and Hipparcos proper motions
J. Maíz Apellániz, M. Pantaleoni González, R. H. Barbá +5
CONTEXT.The first Gaia Data Release (DR1) significantly improved the previously available proper motions for the majority of the Tycho-2 stars. AIMS. We want to detect runaway star…
(sub)Millimeter Emission Lines of Molecules in Born-again Stars
D. Tafoya, J. A. Toalá, W. H. T. Vlemmings +7
The detection and study of molecular gas in born-again stars would be of great importance to understand their composition and chemical evolution. In addition, the molecular emissio…
