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…
Spectral type, temperature and evolutionary stage in cool supergiants
Ricardo Dorda, Ignacio Negueruela, Carlos González-Fernández +1
In recent years, temperature scales in cool supergiants (CSGs) have been disputed, and the possibility that spectral types (SpTs) do not depend primarily on temperature has been ra…
A new survey of cool supergiants in the Magellanic Clouds
Carlos González-Fernández, Ricardo Dorda, Ignacio Negueruela +1
In this study, we conduct a pilot program aimed at the red supergiant population of the Magellanic Clouds. We intend to extend the current known sample to the unexplored low end of…
