The Gaia view on massive stars: EDR3 and what to expect from DR3
J. Maíz Apellániz, R. H. Barbá, M. Pantaleoni González +7
At the time of this meeting, the latest Gaia data release is EDR3, published on 3 December 2020, but the next one, DR3, will appear soon, on 13 June 2022. This contribution describ…
Lucky spectroscopy, an equivalent technique to Lucky Imaging: II. Spatially-resolved intermediate-resolution blue-violet spectroscopy of 19 close massive binaries using the William Herschel Telescope
J. Maíz Apellániz, R. H. Barbá, C. Fariña +5
CONTEXT. Many massive stars have nearby companions whose presence hamper their characterization through spectroscopy. AIMS. We want to continue obtaining spatially resolved spectro…
MONOS: Multiplicity Of Northern O-type Spectroscopic systems. I. Project description and spectral classifications and visual multiplicity of previously known objects
J. Maíz Apellániz, E. Trigueros Páez, I. Negueruela +14
[ABRIDGED] AIMS. MONOS is collecting information and studying O-type spectroscopic binaries with delta > -20 deg. In this 1st paper we describe the sample and provide spectral clas…
Lucky Spectroscopy, an equivalent technique to Lucky Imaging. Spatially resolved spectroscopy of massive close visual binaries using the William Herschel Telescope
J. Maíz Apellániz, R. H. Barbá, S. Simón-Díaz +4
CONTEXT: Many massive stars have nearby companions whose presence hamper their characterization through spectroscopy. AIMS: We want to obtain spatially resolved spectroscopy of clo…
The Galactic O-Star Spectroscopic Survey (GOSSS). III. 142 additional O-type systems
J. Maíz Apellániz, A. Sota, J. I. Arias +9
This is the third installment of GOSSS, a massive spectroscopic survey of Galactic O stars, based on new homogeneous, high signal-to-noise ratio, R~2500 digital observations select…
Spectroscopic and photometric analysis of the early-type spectroscopic binary HD 161853 in the centre of an H II region
R. Gamen, C. Putkuri, N. I. Morrell +6
We study the O-type star HD 161853, which has been noted as a probable double-lined spectroscopic binary system. We secured high-resolution spectra of HD 161853 during the past nin…
