Star formation begins in molecular clouds. These environments are favorable for star formation because of their. These conditions allow clumps to collapse into protostars because can overcome Throughout the process of collapse, the interior temperature increases. Eventually, the rate of contraction slows because fights to overcome in the now-hot interior. The main sequence star now maintains a balance between gravity and pressure, a state called. This overall process is the same for all stars, but it happens most quickly for.
