PHASES OF A STAR:
heavenly bodies in your not-so-friendly galactic neighbourhood.............
Beware,in a few 100 million years ,our fate could rest upon one of these , with our own friendly sun,turning on full-throttle against us....................................
Read on...........
 
 
Evolution of stars
The life cycles of stars follow three general patterns, each associated with a range of initial mass. There are (1) high-mass stars, which have more than 8 solar masses; (2) intermediate-mass stars, with 0.5 to 8 solar masses -- the group that includes the sun; and (3) low-mass stars, with 0.1 to 0.5 solar mass. Objects with less than 0.1 solar mass do not have enough gravitational force to produce the core temperature necessary for hydrogen fusion.
The life cycles of single stars are simpler than those of binary systems, so this section discusses the evolution of single stars first. And because astronomers know much more about the sun than any other star, the discussion begins with the development of intermediate-mass stars.
