Population III stars were, until recently, a hypothetical class of stars that were presumed to be the very first generation of stars formed after the Big Bang. Because they were formed when the Big Bang was still so recent that the interstellar medium was still very warm, and universe was still essentially devoid of any element heavier than helium or lithium, these stars can be much larger and more massive than any star formed more recently, and have some unusual behavior and physical properties.
It is hypothetical no longer. Apparently supernovae with characteristics indicating it’s progenitor star were massive population III stars have been found,
