Yes, our star will become a red super giant, then a white dwarf finally ending up a black dwarf and stars form from supernova nebula which is an exploded star.
A star can orbit around another star in what is called a binary system.
Technically, one star isn't orbiting the other -- they are orbiting each other.
We just started learning this at school....there is alot of steps to it. The protostar starts in the nebula. Here is a few:Do you mean like how does a low/medium mass protostar form to a low/medium...
Two stars that are close together will orbit each other. More precisely, they will orbit around their common center of mass. The two stars are called a binary star in this case.
