What is the temperature of a protostar?
the color of the protostar is red
Why does the temperature of a protostar increase?
As gravity pulls more material toward the center of the protostar, the pressure inside the protostar builds.
How long does a protostar live?
A protostar will live as long as 100,000 years. After material stops falling on the protostar it will enter then T Tauri star phase.
When does a forming star become stable?
Usually, gravitational collapse of the protostar is stopped after hydrogen fusion starts in the center. Then gravitational forces and radiation pressure are in equilibrium.
Will a protostar form near the end of a star's life cycle?
No, a protostar is basically the BEGINNING of a star's life cycle.
Why doesnt a protostar form a black hole?
The pressure within a protostar counters gravity and prevents the star from collapsing further.
What is a binary protostar?
"Binary" means there are two stars. And "protostar" means the stars are in an early, or preliminary, stage.
What does the word strongmen means?
The strong men are the two forces within.
What is the temperature of a protostar?
the color of the protostar is red
The earliest stage of a stars life is called a?
A Protostar.

Are protostar a star?
A protostar is more like a stage previous to a star - before it ignites.
What is the life span of protostar?
A protostar takes about 100,000 years to reach the main sequence.
How hot must the core of a protostar be to begin nuclear fusion?
When the core of a protostar has reached about 10 million K, pressure within is so great that nuclear fusion of hydrogen begins, and a star is born.
Was the Sun a protostar about a million years ago?
No. The sun was a protostar about 4.6 billion years ago.
