What occurs when a supergiant explodes?

What occurs when a supergiant explodes?

Supernova. The supergiant explodes as a supernova. The outer layers are blown off into space leaving behind the star’s core, which begins to shrink.

What happens when a red giant expands and is blown away?

Eventually all of the hydrogen gas in the outer shell of the Red Giant is blown away by stellar winds to form a ring around the core. This ring is called a planetary nebula. The core is now a hot white dwarf star.

Which object forms when a supergiant explodes ?\?

After a super giant explodes some material is left behind. This material may form a neutron star. Neutron stars are the remains of high mass stars. They are the smallest and densest stars.

What objects form when a supergiant forms?

A Thorne–Żytkow object is formed when a neutron star collides with another star, typically a red giant or supergiant.

What is it called when a supergiant star explodes?

A supernova is a powerful and luminous explosion of a star. It has the plural form supernovae /-viː/ or supernovas, and is abbreviated SN or SNe. This transient astronomical event occurs during the last evolutionary stages of a massive star or when a white dwarf is triggered into runaway nuclear fusion.

What does a supernova leave behind?

Usually a very dense core is left behind, along with an expanding cloud of hot gas called a nebula. A supernova of a star more than about 10 times the size of our sun may leave behind the densest objects in the universe—black holes.

What is left after a red giant collapses?

After a low- or medium-mass 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 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 black dwarf.

What happens after a super red giant?

Red giant stars collapse to form a white dwarf star that gradually cools over time. Red supergiants quickly collapse, producing a giant explosion called a supernova.

What object will the Sun leave behind after its red giant phase?

After spending about 1 billion years as a red giant, our own sun will become a white dwarf, packing most of its initial mass into a sphere roughly the size of Earth. This fate awaits many other stars as well — all of them that are less than about eight times more massive than the sun, in fact.

What does a red supergiant turn into?

All red supergiants will exhaust the helium in their cores within one or two million years and then start to burn carbon. This continues with fusion of heavier elements until an iron core builds up, which then inevitably collapses to produce a supernova.

What comes after a supergiant star?

Depending on its size, the star becomes either an average star or a massive star. The average star then becomes a red giant, a planetary nebula, and ends its life as a white dwarf. The massive star turns into a red supergiant, goes supernova, and ends up as a neutron star or a black hole – again, depending on its size.

Which object forms when a supergiant runs out of fuel?

When a massive star, a supergiant, runs out of fuel, it dies in a spectacular way. The core of the star suddenly collapses. It heats up dramatically and its outer layers are blasted off into space in a huge explosion called a supernova.

Where do supergiant stars form?

Supergiant stars form out of massive main-sequence stars that have run out of hydrogen in their cores. This causes them to expand greatly, similarly to low-mass stars, however, they begin to fuse helium in their core not long after exhausting their hydrogen supplies.

What do supergiant stars turn into?

They go on to successively ignite heavier elements, usually all the way to iron. Also because of their high masses, they are destined to explode as supernovae.

Can a supergiant become a black hole?

13.1 Supergiants When stars run out of hydrogen to fuse in their cores, stars above about 10 times the mass of the Sun become supergiants and then undergo a supernova, becoming either a neutron star or a black hole.

Why do supergiant stars explode?

As supergiants burn ever more massive elements, their cores become hotter and more pressurized. Ultimately, by the time they start fusing iron and nickel, these stars run out of energy, their cores collapse and they eject their gassy outer atmospheres into space in a violent type II supernova explosion.
