Polluting the pair-instability mass gap for binary black holes through super-Eddington accretion in isolated binaries

L. A. C. van Son, S. E. de Mink, F. S. Broekgaarden +6

The theory for single stellar evolution predicts a gap in the mass distribution of black holes (BHs) between approximately 45-130M${}_{\odot }$, the so-called "pair-instability mass g…
