New Cepheid variables in the young open clusters Berkeley 51 and Berkeley 55
M. E. Lohr, I. Negueruela, H. M. Tabernero +3
As part of a wider investigation of evolved massive stars in Galactic open clusters, we have spectroscopically identified three candidate classical Cepheids in the little-studied c…
Calibrating the metallicity of M dwarfs in wide physical binaries with F-, G-, and K- primaries - I: High-resolution spectroscopy with HERMES: stellar parameters, abundances, and kinematics
D. Montes, R. González-Peinado, H. M. Tabernero +7
We investigated almost 500 stars distributed among 193 binary or multiple systems made of late-F, G-, or early-K primaries and late-K or M dwarf companion candidates. For all of th…
NGC 3105: a young open cluster with low metallicity
J. Alonso-Santiago, A. Marco, I. Negueruela +4
NGC 3105 is a young open cluster hosting blue, yellow and red supergiants. This rare combination makes it an excellent laboratory to constrain evolutionary models of high-mass star…
Berkeley 51, a young open cluster with four yellow supergiants
Ignacio Negueruela, Maria Monguió, Amparo Marco +3
The heavily obscured open cluster Berkeley~51 shows characteristics typical of young massive clusters, even though the few previous studies have suggested older ages. We combine op…
An LTE effective temperature scale for red supergiants in the Magellanic clouds
H. M. Tabernero, R. Dorda, I. Negueruela +1
We present a self-consistent study of cool supergiants (CSGs) belonging to the Magellanic clouds. We calculated stellar atmospheric parameters using LTE KURUCZ and MARCS atmospheri…
