MONOS.II. Orbit review and analysis for 35 single-lined spectroscopic binary systems and candidates
E. Trigueros Páez, R. H. Barbá, I. Negueruela +3
[ABRIDGED] AIMS: The MONOS project is collecting information and studying O-type spectroscopic binaries with delta > -20 deg. In this 2nd paper, we tackle the study of the 35 singl…
Double-lined spectroscopic binaries in the APOGEE DR16 and DR17 data
Marina Kounkel, Kevin R. Covey, Keivan G. Stassun +25
APOGEE spectra offer 1 km s precision in the measurement of stellar radial velocities (RVs). This holds even when multiple stars are captured in the same spectrum,…
Spatially resolved spectroscopy of close massive visual binaries with HST/STIS: I. Seven O-type systems
J. Maíz Apellániz, R. H. Barbá
CONTEXT. Many O-type stars have nearby companions whose presence hamper their characterization through spectroscopy. AIMS. We want to obtain spatially resolved spectroscopy of clos…
Spectroscopic study of the extremely young O-type triple system Herschel 36 A in the Hourglass Nebula. I. Orbital properties
Abdo R. Campillay, Julia I. Arias, Rodolfo H. Barbá +3
We present a detailed spectroscopic study of Herschel 36 A (H36A), the main stellar component of the massive multiple system Herschel 36 in the Hourglass Nebula, based on high-reso…
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…
GALANTE: finding all the optically accessible Galactic O+B+WR stars in the Galactic Plane
J. Maíz Apellániz, E. J. Alfaro, R. H. Barbá +8
GALANTE is an optical photometric survey with seven intermediate/narrow filters that has been covering the Galactic Plane since 2016 using the Javalambre T80 and Cerro Tololo T80S…
