Скачать или смотреть Population III Stars | The First Stars in the Universe

Just before the Reionization Era...

For the first time, the universe lit up with the formation
of the very first stars, the Population III Stars. These stars are composed entirely of primordial gas, hydrogen, helium and very small amounts of lithium and beryllium. Collapsing gases during the formation of proto-galaxies mostly led to the formation of these hypergiant stars.

These hypothetical stars are expected to have a mass of about several hundred solar mass, which might be the reason to why they have not been observed yet. Hypermassive stars usually have shorter lifespans, for they rapidly exhaust their fuel, leaving behind their dead corpses in the form of white dwarfs, neutron stars or black holes. Moreover, the hypermassive ones would have gone pair-instability supernova, radiating out extreme amounts of energy and leaving behind no remnants.

These stars are expected to have extremely low metallicities. Owing to their high masses, they radiated mostly in the ultraviolet spectrum. Although none have been spotted till date, the search for these stars continues.
