The first stage of a star is the nebulae. The nebulae are made up of huge clouds of dust and gas. (Buzzle) The amount of gas and dust in a star determines the size of the star. As the star gets more dust and gas, gravity is forming in the star and a protostar is made. The stars temperature is about 15,000,000 degrees celsius. Nuclear fusion begins and the star starts to give off light. The star is in the main sequence. The main sequence is where most of the stars life is spent. A red giant is formed when the hydrogen in its core depletes. The core then loses stability and expands and becomes less bright. The star then will become a white dwarf. After the star loses all its energy it becomes a black dwarf. The stars next stage is a neutron star. The last stage is a black hole.
Lots of detail about the temperture of a star and its life. The first stage the nebula, then a protostar, main sequence white dwarf, black dwarf, neutron star, and lastly the black hole. Almost each stage the star loses energy.
ReplyDeletehow a star dies is when all of its fuel runs out and the gravitey cruses it and turns into a blackhole
ReplyDeleteAnd it also depends on the mass of tthe star. If its mass is 8 or less, like our sun is, then it will have that sequence. If it has a larger mass than 8 its sequence will be a little different.
