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…
CAFÉ-BEANS: An exhaustive hunt for high-mass binaries
I. Negueruela, J. Maíz Apellániz, S. Simón-Díaz +11
CAFÉ-BEANS is an on-going survey running on the 2.2 m telescope at Calar Alto. For more than two years, CAFÉ-BEANS has been collecting high-resolution spectra of early-type stars w…
Orbital and physical properties of the Ori Aa,Ab,B triple system
Simón-Díaz, J. A. Caballero, J. Lorenzo +11
We provide a complete characterization of the astrophysical properties of the Ori Aa,Ab,B hierarchical triple system, and an improved set of orbital parameters for the highly e…
Rotation, spectral variability, magnetic geometry and magnetosphere of the Of?p star CPD -28 2561
G. A. Wade, R. H. Barbá, J. Grunhut +14
We report magnetic and spectroscopic observations and modeling of the Of?p star CPD -28 2561. Using more than 75 new spectra, we have measured the equivalent width variations and e…
The new Wolf-Rayet binary system WR62a
A. Collado, R. Gamen, R. H. Barbá
Context. A significant number of the Wolf-Rayet stars seem to be binary or multiple systems, but the nature of many of them is still unknown. Dedicated monitoring of WR stars favou…
