I have been reading about and contemplating the early stages of star formation lately. An interstellar cloud collapses under it's own gravity to form a star. There is much data about what could trigger it, and what happens when the gas heats up or starts fusing. However, i couldn't find anything that answers what would the collapse look like from the inside. Specifically, is there a point during it where the gas is at around atmospheric pressure? Logically, there should be such a point... Would that point last, and for how long? What sort of temperature would there be inside of it? The numbers i've seen list temperature of 2000 *C at much lower density. All in all, i imagined a place that is a gas cloud in interstellar space that is slowly collapsing, which someone stumbled upon while it had earth-like pressure at it's center, and wondered if something like that could actually exist.
