On the origin of the short-period Blue Straggler Stars in Collinder 261: a binary evolution approach
M. Echeveste, M. J. Rain, G. Carraro +3
Building on the recent publication of a fresh catalog of blue straggler stars in Galactic open clusters using Gaia DR3, we conduct a study focusing on the blue straggler stars with…
The IACOB project XVIII. Prevalence of short-period binaries among Galactic helium rich O-type stars
C. Martínez-Sebastián, R. Gamen, O. G. Benvenuto +6
For decades, the origin of helium enrichment in O-type stars has remained an open question. In this study, we investigate the correlation between surface helium abundance and orbit…
Impact of stellar rotation on type II supernova progenitor masses from pre-explosion imaging
L. Martinez, O. G. Benvenuto, M. A. De Vito
The initial masses of red supergiant (RSG) type II supernova (SN II) progenitors are commonly inferred from pre-explosion imaging by converting the progenitor luminosity into an in…
Binary origin of blue straggler stars in Galactic star clusters
M. J. Rain, M. S. Pera, G. Perren +5
Building on the recent release of a new \emph{Gaia}-based blue straggler star catalog in Galactic open star clusters (OCs), we explored the properties of these stars in a cluster s…
Apsidal motion in massive close binary systems. I. HD 165052 an extreme case?
G. Ferrero, R. Gamen, O. G. Benvenuto +1
We present a new set of radial-velocity measurements of the spectroscopic binary HD 165052 obtained by disentangling of high-resolution optical spectra. The longitude of the perias…
The evolution of low mass, close binary systems with a neutron star component: a detailed grid
M. A. De Vito, O. G. Benvenuto
In close binary systems composed of a normal, donor star and an accreting neutron star, the amount of material received by the accreting component is, so far, a real intrigue. In t…
Evolution of low mass close binary systems with a neutron star: its dependence with the initial neutron star mass
M. A. De Vito, O. G. Benvenuto
We construct a set of binary evolutionary sequences for systems composed by a normal, solar composition, donor star together with a neutron star. We consider a variety of masses fo…
