An absence of binary companions to Wolf-Rayet stars in the Small Magellanic Cloud: implications for mass loss and black hole masses at low metallicity
A. Schootemeijer, T. Shenar, N. Langer +5
In order to predict the black hole mass distributions at high redshift, we need to understand whether very massive single stars ( M) at low metallicity lose their…
