The First Stars May Have Weighed More Than 100,000 Suns - by PaulMattSutter
. And you have to do it without raising the temperature of the material, because warmer material will prevent itself from collapsing. So you need some method of removing heat from material as it collapses very quickly.
Earlier simulations had found the appearance of dense pockets within early galaxies that cool off rapidly from emitting radiation, but did not have the resolution needed to follow their further evolution. The new research takes it a step further by examining how the cold dense pockets that initially form in the early universe behave.
This simulations revealed that large flows of cold, dense matter can strike an accretion disk at the center of giant clumps of matter. When that happens a shockwave forms. That shockwave rapidly destabilizes the gas and triggers theThose large pockets can be tens of thousands times more massive than the Sun, and in some cases even 100,000 times more massive than the Sun. With nothing to stop their collapse, they immediately form gigantic stars, known as supermassive stars.
The astronomers do not yet know if supermassive stars formed in the early universe. They hope that future observations with the will reveal clues as to the formation of the first stars and galaxies and determine if these monsters appeared in the infant universe.
