Formation of rotating supergiants via stellar mergers in dense clusters: Implications for black hole natal spins
Stellar mergers with mass ratio q≳0.3 in young clusters can produce blue-supergiant progenitors that leave black holes with dimensionless spins a≃0.5–0.8, reducing post-merger retention and hierarchical-merger rates.
