Astronomy Stars, Black Holes, and Galaxies Life and Death of Stars 1 Answer chandramohanPanakkal Dec 28, 2015 The fusion reaction releases energy and it push the matter inside the star outwards and gravity pulls the matter inwards. Explanation:Chemists have found that there is a mathematical relationship that exists between the concentration of the reactants and products, once equilibrium has been reached, that is independent of the initial concentration of the participants. For any general reaction, aA + bB ⇌ cD + dD (15.3.1) (15.3.1) aA + bB ⇌ cD + dD.Stellar interiors. Models of the internal structure of stars—particularly their temperature, density, and pressure gradients below the surface—depend on basic principles explained in this section. It is especially important that model calculations take account of the change in the star’s structure with time as its hydrogen supply is gradually converted into helium.

This is crucial for our understanding of stellar evolution because it implies that we can describe stellar evolution by a sequence of hydrostatic equilibrium models with slowly varying chemical structure and energy production. 9.1. The Dynamical Timescale
