WebWhen the core runs out of the fuel, the core contracts to generate the heat. Then the heavier elements starts fusing. When the hydrogen in its core is runs out, the heavier element such as helium can start burn to reignite. This causes the generation of excess heat too. So, the given all options are correct. So, the correct option is d. WebJul 3, 2024 · Later, as it runs out of fuel and energy, the star contracts in on itself, and becomes a white dwarf. How Stars Die The next phase in the star's evolution depends on its mass because that dictates how it will end. A low-mass star, like our Sun, has a different fate from stars with higher masses.

WebTHE DEATH OF A LOW OR MEDIUM MASS STAR After a low or medium mass or star has become a red giant the outer parts grow bigger and drift into space, forming a cloud of gas called a planetary nebula. The blue-white hot core of the star that is left behind cools and becomes a white dwarf. The white dwarf eventually runs out of fuel and dies as a ... WebWhen the core runs out of helium to burn, it and the gas around it contracts. This ignites the helium in the shell around the core. Thus, there are two burning shells (the helium burning shell, surrounded by the hydrogen burning shell). The star's luminosity and size both increase. But, eventually the star runs out of fuel.
