Powerful explosions at Z = 0?
Abstract
Metal-free stars are assumed to evolve at constant mass because of the very low stellar winds. This leads to large CO-core mass at the end of the evolution, so primordial stars with an initial mass between 25 and 85 M⊙ are expected to end as direct black holes, the explosion energy being too weak to remove the full envelope.
