Variability of OB stars from TESS southern Sectors 1-13 and high-resolution IACOB and OWN spectroscopy
S. Burssens, S. Simón-Díaz, D. M. Bowman +6
Lack of high-precision long-term continuous photometric data for large samples of stars has prevented the large-scale exploration of pulsational variability in the OB star regime.…
A detailed non-LTE analysis of LB-1: Revised parameters and surface abundances
S. Simón-Díaz, J. Maíz Apellániz, D. J. Lennon +8
LB-1 has recently been proposed to be a binary system at 4 kpc consisting of a B star of 8 Msol and a massive stellar black hole of 70 Msol. This finding challenges our current the…
Stars and brown dwarfs in the sigma Orionis cluster. IV. IDS/INT and OSIRIS/GTC spectroscopy and Gaia DR2 astrometry
J. A. Caballero, A. de Burgos, F. J. Alonso-Floriano +3
Context. Only a few open clusters are as important for the study of stellar and substellar objects, and their formation and evolution, as the young sigma Orionis cluster. However,…
