Clues on the presence and segregation of very massive stars in the Sunburst Lyman-continuum cluster at z=2.37
U. Mestric, E. Vanzella, A. Upadhyaya +15
We report the identification of very massive stars (VMS; mass \,\msun) that may be segregated in the center of the young massive star cluster at =2.37 hosted in the lense…
Spectroscopic evolution of very massive stars at Z = 1/2.5 Zsun
F. Martins, A. Palacios
Stars with masses in excess of 100 Msun are observed in the Local Universe, but they remain rare objects. Because of the shape of the mass function, they are expected to be present…
Spectroscopic evolution of massive stars near the main sequence at low metallicity
F. Martins, A. Palacios
We present synthetic spectra and SEDs computed along evolutionary tracks at Z=1/5 Zsun and Z=1/30 Zsun, for masses between 15 and 150 Msun. We predict that the most massive stars a…
Extreme resonance line profile variations in the ultraviolet spectra of NGC 1624-2: probing the giant magnetosphere of the most strongly magnetized known O-type star
A. David-Uraz, C. Erba, V. Petit +12
In this paper, we present high-resolution HST/COS observations of the extreme magnetic O star NGC 1624-2. These represent the first ultraviolet spectra of this archetypal object. W…
Spectroscopic evolution of massive stars on the main sequence
F. Martins, A. Palacios
We provide an observational view of evolutionary models in the Hertzsprung--Russell diagram, on the main sequence. For that we computed evolutionary models with the code STAREVOL f…
Massive binaries in the vicinity of Sgr A*
O. Pfuhl, T. Alexander, S. Gillessen +5
A long-term spectroscopic and photometric survey of the most luminous and massive stars in the vicinity of the super-massive black hole Sgr A* revealed two new binaries; a long-per…
