WebFeb 26, 2024 · Thus massive main sequence stars, in which CNO cycle burning dominates and $\alpha>15$, experience a large change in radius during main sequence evolution. In contrast, for stars like the Sun, where H-burning via the pp-chain has $\alpha \sim 4$ , the central temperature increases much more as $\mu$ and $\rho$ increase, and so the … WebCAITY: So if a star is at least eight times the mass of our sun, it will collapse in on itself …

So the atoms (often the element hydrogen) inside the star collide together, going through a process of nuclear fusion, which generates heat, electromagnetic radiation (including visible light), and energy in other forms, such as high-energy particles. This period of atomic burning is what most of us think … See more The stars took a long time to form, as gas drifting in the universe was drawn together by the force of gravity. This gas is mostly hydrogen, because it's … See more As the hydrogen fuel in a star gets converted to helium, and to some heavier elements, it takes more and more heat to cause the nuclear fusion. The mass of a star plays a role in … See more Chandrasekhar determined any star more massive than about 1.4 times our sun (a mass called the Chandrasekhar limit) wouldn't be able to … See more WebThus, the Sun can burn for 3.2x10 17 seconds /3.16x10 7 seconds = about 10 10 years. We can extend this result to other stars by scaling. That is, if a star has 10 solar masses, multiply the above result by 10. If it has 100 solar luminosities, divided the above result by 100. In other words the life time of a star is about 10 10 M/L years.
