Hello,

I have noticed there is quite a lot of different star behaviours.

Are the star properties and behaviour
more or less determined by initial mass and evolution stage ?

Or are there a parallel evolution paths possible ?

I suppose being in binary system
can create other dimension to variability.

How much is eventually in this context significant
difference in initial composition,
like stars of the 1st generation with initial cosmological composition,
versus later generations with some extra helium and heavier elements ?
