Physical Properties of Wolf-Rayet Stars
TL;DR: The striking broad emission line spectroscopic appearance of Wolf-rayet stars has long defied analysis, owing to the extreme physical conditions within their line-and continuum-forminformin...
Journal ArticleDOI
The R136 star cluster hosts several stars whose individual masses greatly exceed the accepted 150 M⊙ stellar mass limit
Paul A. Crowther,O. Schnurr,Raphael Hirschi,Raphael Hirschi,Norhasliza Yusof,Richard J. Parker,Simon P. Goodwin,Hasan Abu Kassim +7 more
TL;DR: In this paper, the mass of hydrogen-rich WN5−6 stars within the young star clusters NGC 3603 and R136 were analyzed using archival Hubble Space Telescope and Very Large Telescope spectroscopy, and high spatial resolution near-IR photometry, including MAD imaging of R136.

TL;DR: In this paper, the multiplicity properties of the massive O-type star population were analyzed using multi-epoch spectroscopy and variability analysis to identify spectroscopic binaries.
Journal ArticleDOI
Realistic ionizing fluxes for young stellar populations from 0.05 to 2 Z
TL;DR: In this article, a new grid of ionizing fluxes for O and Wolf-Rayet (W•R) stars is presented for use with evolutionary synthesis codes and single-star H II region analyses.
