Astrophysical parameters of the peculiar X-ray transient IGR J11215-5952
J. Lorenzo, I. Negueruela, N. Castro +3
The hard X-ray source IGR J11215-5952 is a peculiar transient, displaying very short X-ray outbursts every 165 days. We obtained high-resolution spectra of the optical counterpart,…
TYC 3159-6-1: a runaway blue supergiant
V. V. Gvaramadze, A. S. Miroshnichenko, N. Castro +2
We report the results of optical spectroscopy of a candidate evolved massive star in the Cygnus X region, TYC 3159-6-1, revealed via detection of its curious circumstellar nebula i…
Low-amplitude rotational modulation rather than pulsations in the CoRoT B-type supergiant HD 46769
C. Aerts, S. Simon-Diaz, C. Catala +16
{We aim to detect and interpret photometric and spectroscopic variability of the bright CoRoT B-type supergiant target HD\,46769 (). We also attempt to detect a magnetic fi…
Very Massive Stars (VMS) in the Local Universe
Jorick S. Vink, Alexander Heger, Mark R. Krumholz +25
Recent studies have claimed the existence of very massive stars (VMS) up to 300 solar masses in the local Universe. As this finding may represent a paradigm shift for the canonical…
