Multiplicity of Massive stars in the Milky Way (M3W). I. Project description, UNWIND, application to GLS 11 448, and DIB catalog
J. Maíz Apellániz, R. C. Gamen, G. Holgado +8
(ABRIDGED BUT NOT TOO FAR) Multiplicity is ubiquitous among massive stars and its understanding is constrained by the sample of well-determined orbits. The immediate goal of M3W is…
The OVz stars in NGC 346: distribution, stellar parameters and insights into low-metallicity effects
Leidy Arango, Julia Arias, Gonzalo Holgado +3
OVz stars are identified by their optical spectra, in which the He II 4686 absorption line is stronger than any other He line. This spectral characteristic suggests that these star…
The YMDB catalog: Young massive detached binaries for the determination of high-precision absolute stellar parameters
Pablo Martín-Ravelo, Roberto Gamen, Julia I. Arias +2
Massive stars play a crucial role in the cosmic dynamics and chemical evolution of galaxies, however our understanding of their evolution and properties remains limited. An accurat…
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…
