i have some questions regarding nebulas and protostars:
1) how long does a nebula stay in its form before egniting a protostar? (typically)
2) how long does the protostar stay in its form before it becomes a complete star? (typically)
3) when the protostar initially begins its thermonuclear reactions, does the cloud of gases and derbis remain around it? and if so, how long?
4)does the formation of planets begin in the nebula, and then spiral out of the protostar's orbit later on? or does this formation take place further out?
5) what is the typical size of a nebula? its density? its temperature (near the edges)?
thank you in advance for your responces...
