Stripped-envelope stars in different metallicity environments. II. Type I supernovae and compact remnants

Understand

Stripped-envelope stars can be observed as Wolf-Rayet (WR) stars, or as less luminous hydrogen-poor stars with low mass loss rates and transparent winds.

• Both types are potential progenitors of Type I core-collapse supernovae (SNe).
• We use grids of core-collapse models obtained from helium stars at different metallicities to study the effects of metallicity on the transients and remnants these stars produce.
• We characterise the surface and core properties of our core collapse models, and investigate their explodability employing three criteria.
