On the main sequence massive stars quizlet
Web22 de jul. de 2024 · Main sequence stars provide their energy by fusing hydrogen atoms together to produce helium. The more massive a star is the more energy it requires to counteract its own gravity. What processes lead up to nuclear fusion in protostars? Fusion: The energy source of stars. WebMassive Stars When a star is more than ten times as massive as the sun, it becomes a Supergiant star. Supergiants have the shortest lifespans of any star, as the temperatures in a supergiant's core get so high that it is able to fuse the helium that is left over after hydrogen burning has stopped.

WebAs shown in the Hertzsprung-Russell Diagram, Main Sequence stars span a wide range of luminosities and colors, and can be classified according to those characteristics. The smallest stars, known as red dwarfs, may contain as little as 10% the mass of the Sun and emit only 0.01% as much energy, glowing feebly at temperatures between 3000-4000K.
