Death of high mass stars
WebApr 11, 2024 · We saw that stars whose core masses are less than 1.4 M Sun at the time they run out of fuel end their lives as white dwarfs. Dying stars with core masses between 1.4 and about 3 M Sun become neutron stars. But there are stars whose core masses are greater than 3 M Sun when they exhaust their fuel supplies. What becomes of them?

WebMar 15, 2016 · Stars with higher masses about 1.4 to 2.8 times the mass of the Sun will have so much gravity that they will collapse even further than the white dwarf Stage until the collapse will be contained by the Neutrons formed inside the core due to extreme compression. This is called a Neutron Star and has a size of rougly 20km. WebHigh-mass stars are very luminous and short lived. ... Death: Supernova. High-mass stars die in spectacular explosions called supernovas. A supernova spews more than 90 percent of the star’s mass, including the newly formed heavy elements, out into the galaxy.

WebThe minimum initial mass for stars that die the most violent deaths is: 8 M⊙ Which of the following observations have NOT helped to confirm supernova theory? Neutron degeneracy pressure The collapse of the core of a massive star takes roughly One second Iron fusion does NOT occur in the core of a massive star because: WebThe star's core runs out of hydrogen atoms to fuse and the lack of outward force causes the core to contract, becoming much hotter and denser. How does the gravitational pull of a red giant compare to that of a main sequence star of similar mass? From an equal distance they are about the same but the pull at the surface of a red giant is much ...
WebStars with high masses live longer that stars with lower masses. False Our sun will end its life in a planetary nebula and become a white dwarf. True The most massive stars generate energy at the end of their lives by fusing iron in their cores. False The heaviest element produced by stars or in supernovae is silicon. False WebApr 11, 2024 · But the death of each massive star is an important event in the history of its galaxy. The elements built up by fusion during the star’s life are now “recycled” into space by the explosion, making them available to enrich the gas and dust that form new stars …
