The IACOB project: CVIII. Hunting for spectroscopic binaries in the O and B supergiant domain.The threat of pulsational variability
S. Simón-Díaz, N. Britavskiy, N. Castro +2
Observations have definitively strengthened the long-standing assertion that binaries are crucial in massive star evolution. While the percentage of spectroscopic binary systems am…
Gaia colour-magnitude diagrams of young open clusters: Identification in the UBC catalogue and a comparison of manual and automated analysis
Ignacio Negueruela, Abel de Burgos
Automated analysis of Gaia astrometric data has led to the discovery of many new high-quality open cluster candidates. With a good determination of their parameters, these objects…
Hubble spectroscopy of LB-1: comparison with B+black-hole and Be+stripped-star models
D. J. Lennon, J. Maíz Apellániz, A. Irrgang +10
LB-1 has variously been proposed as either an X-ray dim B-type star plus black hole (B+BH) binary, or a Be star plus an inflated stripped star (Be+Bstr) binary. The Space Telescope…
Spectroscopic classification of a complete sample of astrometrically-selected quasar candidates using Gaia DR2
K. E. Heintz, J. P. U. Fynbo, S. J. Geier +20
Here we explore the efficiency and fidelity of a purely astrometric selection of quasars as point sources with zero proper motions in the {\it Gaia} data release 2 (DR2). We have b…
High-resolution spectroscopic study of massive blue and red supergiants in Per OB1
A. de Burgos, S. Simón-Díaz, D. J. Lennon +5
The Perseus OB1 association hosts one of the most populous groupings of blue and red supergiants (Sgs) in the Galaxy. We discuss whether the massive O-type and blue/red Sg stars lo…
