A massive star ends with a violent explosion called a supernova. The matter ejected in a supernova explosion becomes a glowing supernova remnant.

What do massive stars end their life as?
Stars die because they exhaust their nuclear fuel. ... Really massive stars use up their hydrogen fuel quickly, but are hot enough to fuse heavier elements such as helium and carbon. Once there is no fuel left, the star collapses and the outer layers explode as a 'supernova'.
What happens to the most massive stars?
When massive stars die an explosive death, they blow that material off, where it is gathered by other stars and formed into planets. Massive stars are also responsible for neutron stars. After a Wolf-Rayet star explodes, it can leave behind a dense neutron star core.
What happens when a massive star ends its life as a supernova?
The Supernova Giveth and the Supernova Taketh Away. After the supernova explosion, the life of a massive star comes to an end. ... 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 and planets.
What causes Hypernova?
A hypernova (alternatively called a collapsar) is a very energetic supernova thought to result from an extreme core-collapse scenario. In this case a massive star (>30 solar masses) collapses to form a rotating black hole emitting twin energetic jets and surrounded by an accretion disk.
What is the end product of all low mass stars and medium mass stars?
Stars that have a lot of mass may end their lives as black holes or neutron stars. A low or medium mass star (with mass less than about 8 times the mass of our Sun) will become a white dwarf. A typical white dwarf is about as massive as the Sun, yet only slightly bigger than the Earth.
What type of stars end up as supernovae?
Binary stars are two stars that orbit the same point. One of the stars, a carbon-oxygen white dwarf, steals matter from its companion star. Eventually, the white dwarf accumulates too much matter. Having too much matter causes the star to explode, resulting in a supernova.
What remains of a massive star after it explodes as a supernova quizlet?
After a Supernova the star will become a Neutron Star, giving off very little light. If it is big enough the Star could collapse in on it self making it a Black Hole. We have recently found that anything with enough gravity can collapse in on it self and become a Black Hole, so even you or I could.
What is a massive star supernova?
A supernova is the biggest explosion that humans have ever seen. Each blast is the extremely bright, super-powerful explosion of a star. A supernova is the biggest explosion that humans have ever seen. Each blast is the extremely bright, super-powerful explosion of a star.
How big is a Kilonova?
The term kilonova was introduced by Metzger et al. in 2010 to characterize the peak brightness, which they showed reaches 1000 times that of a classical nova. They are 1⁄10 to 1⁄100 the brightness of a typical supernova, the self-detonation of a massive star.
What is Meganova?
A meganova was a stellar event presumably greater than a supernova.
What's the difference between a supernova and a Kilonova?
SUPERNOVA: the explosion of a massive star dying or of a white Dwarf getting too big. They produce the star stuff we are made of like calcium! KILONOVA: The explosion resulting from the merger of two Neutron Stars!
What is the end product of the life of a low mass star?
The end product of the life of a low mass star, such as our own Sun, is a brown dwarf. This is simply a star that has exhausted its nuclear fuel once it begins to fuse helium into lithium (our own star is currently fusing hydrogen into helium) and can no longer sustain fusion.
What is the final stage of a low mass star?
For low-mass stars (left hand side), after the helium has fused into carbon, the core collapses again. As the core collapses, the outer layers of the star are expelled. A planetary nebula is formed by the outer layers. The core remains as a white dwarf and eventually cools to become a black dwarf.
How does the life and death of a high mass star differ from the life and death of a low mass star?
Both, a low mass Star and a High mass Star will Start off with fusing hydrogen into Helium, though a high mass Star will burn it faster because of increased pressure and temperature in the core. A second difference is the ability to create heavier elements.
When a large star becomes a supernova?
A massive star goes supernova when it runs out of nuclear fuel.
Which stars become neutron stars?
Any main-sequence star with an initial mass of above 8 times the mass of the sun (8 M ☉) has the potential to produce a neutron star. As the star evolves away from the main sequence, subsequent nuclear burning produces an iron-rich core.
Which stage in the life cycle of a star lasts the longest?
The T Tauri phase lasts for about 100 million years, after which the star will enter the longest phase of its development – the Main Sequence phase.
