(ORDO NEWS) — Computer simulations have shown that supermassive stars formed in the early universe, with masses up to 100,000 times the mass of the sun.
For years, astronomers have puzzled over what the typical size of the first stars was. Recently, a group of researchers took advantage of computer simulations and got a surprising result.
Their model considered cold accretion. To create a large star, you need to collect a lot of material very quickly into a very small volume. And this must be done without raising the temperature of the material.
Earlier models have found dense pockets inside young galaxies.
However, scientists have not been able to track their further evolution. In a new study, scientists are studying how cold, dense pockets that form in the early universe behave.
Simulations have shown that large flows of cold dense matter can hit the accretion disk at the center of giant clumps of matter.
When this happens, a shock wave is formed. This shock wave quickly destabilizes the gas and causes large agglomerations of matter to collapse instantly.
These large pockets can be up to 100,000 times as massive as the Sun in some cases. They form supermassive stars.
Astronomers do not yet know if supermassive stars formed in the early universe.
They hope that future observations with the James Webb Space Telescope will provide clues to the formation of the first stars and galaxies.
