2008年2月13日 · We show that the masses of WNH stars are systematically higher than H-poor WR stars (both WN and WC), with little overlap, while H mass fractions of luminous WNH stars …

Wolf–Rayet stars, often abbreviated as WR stars, are a rare heterogeneous set of stars with unusual spectra showing prominent broad emission lines of ionised helium and highly ionised …

2017年9月18日 · Luminous blue variables (LBVs) had long been considered massive stars in transition to the Wolf–Rayet (WR) phase, so their identification as progenitors of some peculiar …

We propose the new designation "WNH" for luminous Wolf-Rayet (WR) stars of the nitrogen sequence with hydrogen in their spectra. These have been commonly referred to as WNL …

We propose the new designation ‘‘WNH’’ for luminous Wolf-Rayet (WR) stars of the nitrogen sequence with hydrogen in their spectra. These have been commonly referred to as WNL …

This reinforces the uncertain relation of the LBV phenomenon with the evolution of massive stars because, if we consider redwards expansion as a physical phenomenon, instead of a …

We propose the new designation “WNH” for luminous Wolf-Rayet (WR) stars of the nitrogen sequence with hydrogen in their spectra. These have been commonly referred to as WNL …

Also, the hydrogen mass fractions of the most luminous WNH stars are higher than those of luminous blue variables (LBVs). These two trends favor the interpretation that the most …

We show that the masses of WNH stars are systematically higher than H-poor WR stars (both WN and WC), with little overlap, while H mass fractions of luminous WNH stars exceed those of …
