A VLT/FLAMES survey for massive binaries in Westerlund 1 V. the X-ray selected blue stragglers Wd1-27 and -30a
J. S. Clark, F. Najarro, I. Negueruela +3
Observational studies suggest that many OB stars are found within binary systems which may be expected to interact during their lifetimes. Significant mass transfer or merger of bo…
An atlas of cool supergiants from the Magellanic Clouds and typical interlopers. A guide for the classification of luminous red stars
Ricardo Dorda, Ignacio Negueruela, Carlos González-Fernández +1
We present an atlas composed of more than 1500 spectra of late-type stars (spectral types from G to M) observed simultaneously in the optical and calcium triplet spectral ranges. T…
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…
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…
A search for Galactic runaway stars using Gaia Data Release 1 and Hipparcos proper motions
J. Maíz Apellániz, M. Pantaleoni González, R. H. Barbá +5
CONTEXT.The first Gaia Data Release (DR1) significantly improved the previously available proper motions for the majority of the Tycho-2 stars. AIMS. We want to detect runaway star…
An ALMA 3mm continuum census of Westerlund 1
D. M. Fenech, J. S. Clark, R. K. Prinja +6
Massive stars play an important role in both cluster and galactic evolution and the rate at which they lose mass is a key driver of both their own evolution and their interaction w…
