1: A nebula starts to collapse and soon it turns into a swirling disk. Gas goes to the center and starts to form a bright object. This object starts to get denser and hotter. The bright circle in the middle turned bright blue. The gas swirled until the star grew completely then the gas went the other star. Then other gas collided and formed balls of rock and gas. The planets formed and the remaining gas was blown out of the solar system. gravity keeps this new star together.
2: A main sequence star creates nuclear fusion by mixing hydrodgen atoms with helium atom. The main sequence is the longest stage in a stars life. Many scientists believe that our sun is a main sequence star. This star just happens to be the blue star that the incans worshiped as a god in the form of a dragon
4: A blue giant is a massive star that has exausted hydrogen in its core. It is extremly luminous and has absoulute magnatudes of negative five to negative six.They have a surface temperature of over 30,000 kelvin and are ten thousand times more luminous than our sun. The incan star will actually be like this for at least 5 billion more years.
6: When a blue giant collapses then a neutron star half the size of a blue giant will stay there in its place. A neutron star is made when electrons and protons mix together to form neutrons. When a neutron star loses all its fuel it turns into a white dwarf. When a white dwarf burns out it becomes a dead star, but luckily that won't happen to to this star.
7: Deticated to my pet turtle Snappy. He is really cute.
