How much mass for thermonuclear fusion
WebOct 7, 2003 · 0. A protostar will begin gravitational collapse only if the total gravitational potential energy exceeds twice the thermal energy. In other words, a gas has to be sufficiently cool and sufficiently dense to collapse. Also, as the protostar collapses about half of the gravitational PE is converted into heat, and about half is radiated into space.

WebSep 12, 2024 · The Sun’s mass decreases by 0.0276u = 4.58 × 10 − 29kg per fusion reaction, so the rate at which its mass decreases is (9.26 × 1037reaction / s)(4.58 × 10 − 29kg / reaction) = 4.24 × 109kg / s. In 5 × 109y = 1.6 × 1017s, the Sun’s mass will therefore decrease by ΔM = (4.24 × 109kg / s)(1.6 × 1017s) = 6.8 × 1026kg.
