During the evolution of a star, what event takes at least a million years to occur?

After the initial contraction, what happens to the temperature of this gaseous body?

After the initial contraction and when the temperature rises high enough, energy is radiated from the surface in the form of:

The gaseous body that continues to form, now appears as a large red object called a:

A protostar is a developing star not yet hot enough to engage in the process of:

As gravity continues to collapse the forming star, what part is heated more intensely than the outer layer?

When the core of a protostar reaches 10 million degrees Kelvin, the pressure is so great that the nuclear fusion of what gas begins?

The heat from the process of hydrogen fusion causes the motion of the gases to:

As the motion of the gases increases, it causes and increase in the outward:

What does the forming star become when the outward pressure equals the inward force of gravity?
