On the role of the WNH phase in the evolution of very massive stars: Enabling the LBV instability with feedback
Nathan Smith, Peter S. Conti
(abridged) We propose the new designation ``WNH'' for luminous Wolf-Rayet (WR) stars of the nitrogen sequence with H in their spectra. These are commonly called WNL stars (e.g., WN…
