What secondary factor, related to the star's composition, can subtly influence whether it avoids a black hole formation?
Answer
Chemical composition
The presence of heavier elements ('metals') affects how efficiently a star can shed mass during its giant phases; a star that sheds more mass might fall below a critical threshold just before final collapse, altering its final remnant.
