WebbAt this point, hydrogen is converted into helium in the core and the star is born onto the main sequence. For about 90% of its life, the star will continue to burn hydrogen into helium and will remain a main sequence star. Once the hydrogen in the core has all been burned to helium, energy generation stops and the core begins to contract. WebbStars do not simply pop up on the main sequence. Before the stars arrive on the zero-age main sequence, they form in the collapses of molecular clouds, gain matter …

WebbThe Main Sequence is where stars spend most of their lives. Main sequence stars like our sun have a hot, dense core where hydrogen is fused into helium. This heat is transported outwards toward the surface of the star through radiation and convection. Equilibrium There are a number of powerful forces acting on a star.
