How long does it take a star to transition from main sequence to red giant?

WebFusion is the process that powers the sun and the stars. It is the reaction in which two atoms of hydrogen combine together, or fuse, to form an atom of helium. In the process some of the mass of the hydrogen is converted into energy. Thus fusion has the potential to be an inexhaustible source of energy. WebLow-mass stars turn into planetary nebulae towards the end of their red giant phase. At that point the star becomes highly unstable and starts to pulsate. This produces strong stellar winds which throw off the outer layers of the star. The outer layers drift away from the star leaving a small hot, bright core behind, called a white dwarf. The ...
