After the initial contraction and when the temperature rises high enough, energy is radiated from the surface in the form of:
long-wavelength red light
nuclear fusion
rises
core
protostar
initial contraction
hydrogen
gas pressure
As the motion of the gases increases, it causes and increase in the outward:
