The Wolf–Rayet Content of the Galaxies of the Local Group and Beyond
Galaxies, 2019 Wolf−Rayet stars (WRs) represent the end of a massive star’s life as it is about to turn into a supernova. Obtaining complete samples of such stars across a large range of metallicities poses observational challenges, but presents us with an ...

Long GRBs from binary stars: runaway, Wolf-Rayet progenitors [PDF]
, 2007 The collapsar model for long gamma-ray bursts requires a rapidly rotating Wolf-Rayet star as progenitor. We test the idea of producing rapidly rotating Wolf-Rayet stars in massive close binaries through mass accretion and consecutive quasi-chemically ...

Intrinsic polarization of Wolf-Rayet stars due to the rotational modulation of the stellar wind
, 2022 Context. Fast rotating Wolf-Rayet stars are expected to be progenitors of long duration gamma-ray bursts. However, the observational test of this model is problematic.

QUÍMICA ESTELAR E ESTRELAS APOCALÍPTICAS: ESTUDO COMPARATIVO
Colloquium Exactarum, 2012 All atoms existing in the Universe, except Hydrogen (H) and helium (He), arise from processes occurring in stars and their evolution. The stars transmute the H and He in other heavier elements through nuclear fusion and its process rolling, filling and ...

O stars and Wolf-Rayet stars [PDF]
, 1988 Basic information is given about O and Wolf-Rayet stars indicating how these stars are defined and what their chief observable properties are. Part 2 of the volume discussed four related themes pertaining to the hottest and most luminous stars. Presented

High energy processes in Wolf‐Rayet stars [PDF]
Astronomische Nachrichten, 2019 Wolf‐Rayet (WR) stars are massive (≥10 M⊙) evolved stars undergoing advanced nuclear burning in their cores, rapidly approaching the end of their lives as supernovae. Their powerful winds enrich the interstellar medium with heavy elements, providing raw material for future generations of stars.

Radiative driven MHD wind solutions for Wolf-Rayet stars [PDF]
, 2023 A solution for the Wolf-Rayet stars wind is obtained by solving the MHD equations combined with the radiative driven winds formalism. In this model we combine radiation pressure, collimated magnetic fields and centrifugal forces.

Investigating particle acceleration in the Wolf-Rayet bubble NGC 2359
Astronomy & AstrophysicsContext. Massive stars have been proposed as potential major factories of Galactic cosmic rays (GCRs). However, this claim lacks sufficient empirical evidence, especially in the case of isolated stars. The powerful stellar winds from massive stars impact
