The stellar and wind parameters of six prototypical HMXBs and their evolutionary status
R. Hainich, L. M. Oskinova, J. M. Torrejón +7
High-mass X-ray binaries (HMXBs) are exceptional astrophysical laboratories that offer a rare glimpse into the physical processes that govern accretion on compact objects, massive-…
The Wolf-Rayet binaries of the nitrogen sequence in the Large Magellanic Cloud: spectroscopy, orbital analysis, formation, and evolution
T. Shenar, D. P. Sablowski, R. Hainich +11
Massive Wolf-Rayet (WR) stars dominate the radiative and mechanical energy budget of galaxies and probe a critical phase in the evolution of massive stars prior to core-collapse. I…
Testing massive star evolution, star-formation history and feedback at low metallicity : Spectroscopic analysis of OB stars in the SMC Wing
Varsha Ramachandran, W. -R. Hamann, L. M. Oskinova +6
Stars which start their lives with spectral types O and early-B are the progenitors of core-collapse supernovae, long gamma-ray bursts, neutron stars, and black holes. These massiv…
The Galactic WN stars revisited. Impact of Gaia distances on fundamental stellar parameters
W. -R. Hamann, G. Gräfener, A. Liermann +6
Comprehensive spectral analyses of the Galactic Wolf-Rayet stars of the nitrogen sequence (i.e.\ the WN subclass) have been performed in a previous paper. However, the distances of…
On the apparent absence of WR+NS systems: the curious case of WR124
J. A. Toala, L. M. Oskinova, W. -R. Hamann +8
Among different types of massive stars in advanced evolutionary stages is the enigmatic WN8h type. There are only a few Wolf-Rayet (WR) stars with this spectral type in our Galaxy.…
PoWR grids of non-LTE model atmospheres for OB-type stars of various metallicities
R. Hainich, V. Ramachandran, T. Shenar +5
The study of massive stars in different metallicity environments is a central topic of current stellar research. The spectral analysis of massive stars requires adequate model atmo…
