Evolution of a 1 MS-star- HHe burning (main seq.), 9·109y,- evolution towards red giants- He-burning, 109J,- Extended red giatns with
pulsations and heavy mass loss - hot nucleous with planetary nebula- white dwarf, cooling >> 109 y.
Evolution of a 15 MS-star- HHe burning (main seq.), 2·107y- Evolution towards red giant and
strong mass loss,- He, C, O, Si burning, 106 y,- formation of Fe-core,- Core-collapse and supernova-
explosion (for stars with M > 8 MS).
