Can helium burn
WebEnd of Main Sequence Phase: Core hydrogen is all fused into helium. This occurs after about 10 billion years for a G2 type star. Core cools and cannot support mass, therefore core shrinks and heats. ---> hydrogen "burning" spreads. Shell Hydrogen Burning. Solar-mass star passes through later stages of its evolution. WebHelium can be found in certain parts of the world, notably in Texas, as a minor component in some sources of natural gas. The interesting thing is how this gas gets into the ground in the first place. ...
