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

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

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

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

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

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

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

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