Question:

In the first star-forming era after the big band, when
all the stars are composed of hydrogen and helium,
what is thought to be the upper bound for the mass of
H/He supergiant stars? What factors contribute to
this limit/boundary?

If these stars proceed most rapidly to the
(super?)nova state (that's how it works, right?)--and
with it heavy-element (heavier than carbon,
right?)nucleosynthesis--what then is thought to be the
shortest possible stellar 'lifetime'?
