What is the result of a star dying?

What is the result of a star dying?

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 happens to the elements when a star dies?

When stars die, they recirculate some of their material back into the Universe, and that carries with it a mix of heavier elements that were not present when they formed originally. Gas and dust clouds enriched by these newly-formed elements then provide the building blocks for new stars and solar systems.

What is it called when star dies?

THE DEATH OF A HIGH MASS STAR A dying red super giant star can suddenly explode. The explosion is called a supernova. After the star explodes, some of the materials from the star are left behind. This material may form a neutron star.

What happens when a large star dies?

All stars eventually run out of their hydrogen gas fuel and die. The way a star dies depends on how much matter it contains—its mass. While most stars quietly fade away, the supergiants destroy themselves in a huge explosion, called a supernova. The death of massive stars can trigger the birth of other stars.

What are the stages of a dying star?

Small stars, like the Sun, will undergo a relatively peaceful and beautiful death that sees them pass through a planetary nebula phase to become a white dwarf, which eventually cools down over time and stops glowing to become a so-called “black dwarf”.

What are three things that can be left behind after a star dies?

Star Life Cycle

• Planetary Nebula. When a Red Giant dies, the heat and pressure from its core ejects the outer layers of the star into space.
• White Dwarf. The exposed core of a Red Giant that is left behind after the formation of a planetary nebula is known as a white dwarf.
• Supernova.
• Neutron Stars.
• Black Holes.

What happens to a star when it gets old?

Ah, well, when a star like the Sun gets old and becomes a red giant, it expands.

How old are stars when they die?

According to our best available estimates, stars having about 90 percent of the sun’s mass are just now starting to die in the globulars. These stars are most probably around 15 billion years old, but they could conceivably be as young as 12 billion years or as old as 18 billion years.

What happens when a star goes supernova?

When a star goes supernova, a significant amount of its material undergoes fusion is a short period of time. This leads to a massive explosion. Any planets in the vicinity would be exposed to huge temperatures and would be bombarded by huge amounts of radiation and energetic particles.

How do stars die out?

Stars die because they exhaust their nuclear fuel. The events at the end of a star’s life depend on its mass. 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’.
