WebbThe life cycle of a star Gravity and nuclear fusion reactions drive the formation and development of stars. Stars with different masses grow and change throughout the … Webb20 feb. 2024 · Main Sequence Stars - Tau Ceti. If protostars accumulate sufficient mass as they develop, collapsing gas and dust may reach temperatures where hydrogen fuses into helium. Once hydrogen fusion occurs, stars become stable between the competing forces of fusion and gravity and are considered main sequence stars.

Life on the Main Sequence: How Stars Evolve - ThoughtCo

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. http://www.actforlibraries.org/h-r-diagram-and-life-cycle-of-a-star/ WebbStars become main sequence stars when the process of thermonuclear fusion - hydrogen to helium - stabilizes.
