How do giant stars form

WebThis video covers:- How stars form, live and die- How they transition between a nebula, protostar, main sequence star- And then either red giant, white dwarf... WebOne of the best ways to get a "snapshot" of a group of stars is by plotting their properties on an H–R diagram. We have already used the H–R diagram to follow the evolution of protostars up to the time they reach the main sequence. Now we’ll see what happens next.
