TALK: First Stars, Hypernovae, and Faint Supernovae in the early Universe
ABSTRACT:
After the Big Bang, production of heavy elements in the early universe
takes place starting from the formation of the first stars, their
evolution, and explosion. The nature of the first stars, first
supernovae, and first black holes, however, has not been well clarified.
The signature of nucleosynthesis yields of the first stars can be seen
in the elemental abundance patters observed in extremely metal-poor
stars, which show interesting peculiarities relative to the solar
abundance pattern. I will show those peculiar pattern is related to
nucleosynthesis yields of jet-induced explosions, hypernovae associated
with gamma-ray bursts, and possibly superluminous supernovae in the
early universe.
