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 VLT-FLAMES Tarantula Survey XVI. The optical+NIR extinction laws in 30 Doradus and the photometric determination of the effective temperatures of OB stars
J. Maíz Apellániz, C. J. Evans, R. H. Barbá +11
Context: The commonly used extinction laws of Cardelli et al. (1989) have limitations that, among other issues, hamper the determination of the effective temperatures of O and earl…
Studying the kinematics of the giant star-forming region 30 Doradus. I. The data
S. Torres-Flores, R. Barbá, J. Maíz Apellániz +4
We present high-quality VLT-FLAMES optical spectroscopy of the nebular gas in the giant star-forming region 30 Doradus. In this paper, the first of a series, we introduce our obser…
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…
The Galactic O-Star Spectroscopic Survey. I. Classification System and Bright Northern Stars in the Blue-Violet at R~2500
A. Sota, J. Maíz Apellániz, N. R. Walborn +5
We present the first installment of a massive spectroscopic survey of Galactic O stars, based on new, high signal-to-noise ratio, R~2500 digital observations from both hemispheres…
The first orbital solution for the massive colliding-wind binary HD93162 (=WR25)
R. Gamen, E. Gosset, N. Morrell +6
Since the discovery, with the EINSTEIN satellite, of strong X-ray emission associated with HD93162 (=WR25), this object has been predicted to be a colliding-wind binary system. How…
