Why binary interaction does not necessarily dominate the formation of Wolf-Rayet stars at low metallicity

13 Jan 2020 Shenar T. Gilkis A. Vink J. S. Sana H. Sander A. A. C.

Classical Wolf-Rayet (WR) stars are massive, hydrogen depleted, post main-sequence stars that exhibit emission-line dominated spectra. For a given metallicity Z, stars exceeding a certain initial mass M_single(Z) can reach the WR phase through intrinsic mass-loss (single-star channel)... (read more)
