An Orbit for a Massive Wolf–Rayet Binary in the LMC: An Example of Binary Evolution
The Astrophysical JournalWolf–Rayet (WR) stars are helium-burning, evolved massive stars which have had most of their hydrogen-rich outer layers removed, either through stellar winds and/or binary stripping.

Spektra: Jurnal Fisika dan AplikasinyaMassive stars (over 8 solar masses) undergo intricate cosmic journeys. Their evolution, shaped by parameters like stellar wind, rotation velocity, and overshoot, generally includes the pre-main sequence, main sequence, and post-main sequence phases.

On the Hydrogen Abundance in Wolf-Rayet Stars [PDF]
Symposium - International Astronomical Union, 1984 With a semiempirical NLTE-model in spherical geometry we investigate the hydrogen abundance in Wolf-Rayet stars. We find that the flux contribution of the H-Balmer to the He-Pickering lines lies between the usually applied approximate formulae for the optically thin and optically thick case. This result can be understood with our finding that there are

Multiple Shells Around Wolf-Rayet Stars: Space Based Astrometric Observing [PDF]
, 1995 The completion of a complementary optical emission-line survey of the nebulae associated with Wolf-Rayet stars in the southern sky is reported, along with the completion of a survey the large-scale environments of Wolf-Rayet stars using IRAS Skyflux data.

The impact of rotation on the line profiles of Wolf-Rayet stars
, 2013 Context. Massive Wolf-Rayet stars are recognized today to be in a very common, but short, evolutionary phase of massive stars. While our understanding of Wolf-Rayet stars has increased dramatically over the past decades, it remains unclear whether rapid ...

Cool Wolf-Rayet central stars and their planetary nebulae [PDF]
, 1997 The research presented in this thesis is concerned with the properties of Wolf-Rayet central stars and their planetary nebulae (PN). Radial and nebular expansion velocities, reddenings and distances have been derived using different methods.

Wolf-Rayet stars as gamma-ray burst progenitors [PDF]
, 2010 It became clear in the last few years that long gamma-ray bursts are associated with the endpoints of massive star evolution. They occur in star forming regions at cosmological distances (Jakobsson et al., 2005), and are associated with supernova-type ...

The Nature of a Recently Discovered Wolf–Rayet Binary: Archetype of Stripping?
The Astrophysical JournalLMCe055-1 was recently discovered in a survey for Wolf–Rayets (WRs) in the Large Magellanic Cloud, and classified as a WN4/O4, a lower-excitation version of the WN3/O3 class discovered as part of the same survey.

Comparison of Star Clusters With and Without Wolf‐Rayet Stars in Wolf‐Rayet Galaxies
The Astrophysical Journal Supplement Series, 2005 We compare the properties of young star clusters with and without Wolf-Rayet (W-R) stars in W-R galaxies using optical, near-infrared imagery and optical spectroscopy. Our work identifies the clusters with W-R stars in these galaxies for the first time. With this information, comparisons of clusters with and without W-R stars are now possible, enabling

Classification of Wolf–Rayet Stars from LAMOST DR10
The Astrophysical Journal Supplement SeriesWolf–Rayet (WR) stars are highly evolved descendants of the most massive initial stellar populations, serving as essential tracers in stellar evolution. Despite the progress made in their study, a more comprehensive population census is still required to
