What are the stages of star development?

Answer 1

Nebula .Proto star.main sequence.Red giant.White dwarf.

Stars form from a huge cloud of gas and dust known as nebula.
When mass increases due to gravity the temperature and pressure at center goes up.When it reaches about 15 million degree c hydrogen fusion stars..After main sequence when hydrogen is finished the star become red giant and puff out gases.White dwarf remains..More massive stars explodes in supernova become black holes or neutron stars.

Stars go through the following stages of development: 1. Protostar; 2. Main Sequence Star; 3. Red Giant or Supergiant (based on the star's mass); 4. High-mass stars go through planetary nebulas or supernovas; 5. White dwarfs go through low- to medium-mass stars; 6. Black dwarfs (for white dwarfs that have cooled completely).
