What will happen if a massive main sequence star runs out of hydrogen fuel?
When a main sequence star begins to run out of hydrogen fuel, the star becomes a red giant or a red super giant. THE 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.
What happens when a star runs low on fuel?
When stars run out of fuel they begin to collapse rapidly under their own weight. Some stars that are large enough naturally end their lives by exploding in a supernova. Eventually the star will run out of its essential fuel entirely, resulting in its explosive end.
What happens first when a star begins to run out of fuel quizlet?
When a star begins to run out of fuel, its core shrinks and its outer portion expands. Depending on the size the star changes to either a giant or supergiant star.
When a star runs out of energy it will become a?
When the helium fuel runs out, the core will expand and cool. The upper layers will expand and eject material that will collect around the dying star to form a planetary nebula. Finally, the core will cool into a white dwarf and then eventually into a black dwarf. This entire process will take a few billion years.
What is the remnant after a high-mass star dies?
supernova remnants
What do the highest mass stars leave behind?
How does a high-mass star die? -A high-mass star des in a cataclysmic explosion called a supernova, scattering newly produced elements into space and leaving behind a neutron star or black hole.
What happens when a star goes supernova?
This causes the pressure to drop. Gravity wins out, and the star suddenly collapses. Imagine something one million times the mass of Earth collapsing in 15 seconds! The collapse happens so quickly that it creates enormous shock waves that cause the outer part of the star to explode!”
Do stars explode when they are born?
A star is born when atoms of light elements are squeezed under enough pressure for their nuclei to undergo fusion. These heavier atoms are remnants of older stars, which have exploded in an event we call a supernova.
