Wolf–Rayet stars in starburst galaxies
New Astronomy Reviews, 2000 Wolf-Rayet stars have been detected in a large number of galaxies experiencing intense bursts of star formation. All stars initially more massive than a certain, metallicity-dependent, value are believed to experience the Wolf-Rayet phase at the end of their evolution, just before collapsing in supernova explosion.

Symposium - International Astronomical Union, 1982 Sanduleak (1971) has listed five stars, not apparently associated with planetary nebulae, which show very strong 0 VI 3811,34 å emission. He pointed out that two of them are in the Magellanic Clouds and have absolute magnitudes comparable to those of classical (Population I) Wolf-Rayet stars.

The Astronomy and Astrophysics Review, 1992 Recent literature on Population I Wolf-Rayet star research extending from the Milky Way to blue compact dwarf galaxies is reviewed, broken down into inventory, basic parameters and galactic distribution, atmospheres, binaries, intrinsic variability, mass loss, enrichment and evolution.

Newly Discovered Wolf–Rayet Stars in M31
The Astronomical Journal, 2023 The evolved massive star populations of the Local Group galaxies are generally thought to be well understood. However, recent work has suggested that the Wolf–Rayet (WR) content of M31 may have been underestimated.

THE MASSIVE STELLAR POPULATION IN THE DWARF STARBURST GALAXIES
Odessa Astronomical Publications, 2017 The analysis of the long-slit spectral observations of 39 Wolf-Rayet (WR) galaxies with heavy element mass fraction ranging over 2 orders of magnitudes from Z☉/50 to 2Z☉ are presented.

CLOSE BINARY SYSTEMS ON LATE EVOLUTIONARY STAGES
Odessa Astronomical Publications, 2017 Observational and theoretical progress in investigations of close binary stars allow to understand the nature and evolution of many types of close binary systems containing peculiar components: Wolf-Rayet stars, white dwarfs neutron stars and black holes.

(Intrinsic) Variations of Wolf-Rayet Stars [PDF]
Symposium - International Astronomical Union, 1991 Twenty - two Wolf-Rayet stars (12 of type WN and 10 of type UC) were observed in the years 1986-1990 with the VBLUW photometer of Walraven. Eight (WC and WN) objects appeared to be constant. Five of the in total 14 variable objects will be discussed in the present paper: UR46 (WN3 pec), WR50 (WC6+a), WR55 (WN8), WR86 (WC7) and WR123 (WN8).Simultaneous ...

Constraints on the Binarity of the WN3/O3 Class of Wolf–Rayet Stars
The Astrophysical Journal, 2023 The WN3/O3 Wolf–Rayet (WR) stars were discovered as part of our survey for WRs in the Magellanic Clouds. The WN3/O3s show the emission lines of a high-excitation WN star and the absorption lines of a hot O-type star, but our prior work has shown that the
