The Alma catalog of OB stars. II. A cross-match with Gaia DR2 and an updated map of the solar neighbourhood
M. Pantaleoni González, J. Maíz Apellániz, R. H. Barbá +1
We cross-match the Alma catalog of OB stars with Gaia DR2 astrometry and photometry as a first step towards producing a clean sample of massive stars in the solar neighbourhood wit…
Validation of the accuracy and precision of Gaia EDR3 parallaxes with globular clusters
J. Maíz Apellániz, M. Pantaleoni González, R. H. Barbá
CONTEXT. Gaia EDR3 has produced parallaxes for 1.468x10^9 sources but there are calibration issues that require corrections to the published values and uncertainties. AIMS. We want…
Galactic extinction laws: II. Hidden in plain sight, a new interstellar absorption band at 7700 Å broader than any known DIB
J. Maíz Apellániz, R. H. Barbá, J. A. Caballero +2
We have detected a broad interstellar absorption band centred close to 7700 Å and with a FWHM of 176.63.9 Å. This is the first such absorption band detected in the optical ran…
Galactic extinction laws: I. A global NIR analysis with 2MASS photometry
J. Maíz Apellániz, M. Pantaleoni González, R. H. Barbá +2
We have started an ambitious program to determine if the full diversity of extinction laws is real or if some of it is due to calibration or methodological issues. Here we start by…
The high-energy emission from HD~93129A near periastron
S. del Palacio, F. García, D. Altamirano +12
We conducted an observational campaign towards one of the most massive and luminous colliding wind binaries in the Galaxy, HD~93129A, close to its periastron passage in 2018. Durin…
A detailed non-LTE analysis of LB-1: Revised parameters and surface abundances
S. Simón-Díaz, J. Maíz Apellániz, D. J. Lennon +8
LB-1 has recently been proposed to be a binary system at 4 kpc consisting of a B star of 8 Msol and a massive stellar black hole of 70 Msol. This finding challenges our current the…
The GALANTE Photometric System
A. Lorenzo-Gutiérrez, E. J. Alfaro, J. Maíz Apellániz +9
This paper describes the characterization of the GALANTE photometric system, a seven intermediate- and narrow-band filter system with a wavelength coverage from 3000 to 9000 $Å…
Extreme resonance line profile variations in the ultraviolet spectra of NGC 1624-2: probing the giant magnetosphere of the most strongly magnetized known O-type star
A. David-Uraz, C. Erba, V. Petit +12
In this paper, we present high-resolution HST/COS observations of the extreme magnetic O star NGC 1624-2. These represent the first ultraviolet spectra of this archetypal object. W…
The VLT-FLAMES Tarantula Survey
Jorick S. Vink, C. J. Evans, J. Bestenlehner +5
We present a number of notable results from the VLT-FLAMES Tarantula Survey (VFTS), an ESO Large Program during which we obtained multi-epoch medium-resolution optical spectroscopy…
