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…
Lithium abundances as a tracer of AGB stars pollution in the globular cluster NGC 6752
J. Schiappacasse-Ulloa, S. Lucatello, M. J. Rain +1
This paper presents the chemical abundance analysis of 217 stars in the metal-poor globular cluster NGC 6752, distributed from the turn-off to the lower red giant branch. Aluminium…
A new, Gaia based, catalogue of blue straggler stars in open clusters
M. J. Rain, J. Ahumada, G. Carraro
Blue straggler stars are exotic objects present in all stellar environments whose nature and formation channels are still partially unclear. They seem to be particularly abundant i…
The blue straggler population of the open clusters Trumpler 5, Trumpler 20, and NGC 2477
M. J Rain, G. Carraro, J. Ahumada +3
We present a study, based on Gaia DR2, of the population of blue straggler stars (BSS) in the open clusters Trumpler 5, Trumpler 20, and NGC 2477. All candidates were selected acco…
A study of the blue straggler population of the old open cluster Collinder 261
M. J. Rain, G. Carraro, J. A. Ahumada +4
Blue Stragglers are stars located in an unexpected region of the color-magnitude diagram of a stellar population, as they appear bluer and more luminous than the stars in the turno…
Chemical evolution of the metal poor Globular Cluster NGC 6809
M. J. Rain, S. Villanova, C. Muñoz +1
We present the abundances analysis for a sample of 11 red giant branch stars in the metal-poor globular cluster NGC 6809 based on high-resolution spectra. Our main goals are to cha…
