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.

WebOct 15, 2024 · How Do Giant Stars Form? Although giant stars are a different kind of star from average main-sequence stars, it isn’t actually formed right away. Instead, stars go through the main-sequence phase for a long time, perhaps billions of years, before entering the giant phase, which lasts much shorter than the main-sequence phase. WebApr 13, 2024 · The gas and dust that swirl around a star during its formation are critical to forming planets around it. The dust contains heavy elements such as carbon and iron that form the cores of planets. Scientists think planets start off as grains of dust smaller than the width of a human hair. WebScientists think planets, including the ones in our solar system, likely start off as grains of dust smaller than the width of a human hair.
