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…
