What does a low mass or medium mass star eventually become?

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. The blue-white hot core of the star that is left behind cools and becomes a white dwarf.

What do low mass stars eventually become?

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.

What eventually happens to medium mass stars?

Medium-mass stars (less than 3 times the mass of our sun) become a red giants and eventually become a supernova. A supernova is the massive explosion of a star accompanied by emission of light and matter so intense that it can outshine an entire galaxy.

What are the 3 stages of a low mass star?

Low mass star

  • Main Sequence. Low mass stars spend billions of years fusing hydrogen to helium in their cores via the proton-proton chain.
  • Red Giant. When hydrogen fusion can no longer happen in the core, gravity begins to collapse the core again.
  • Planetary Nebula.
  • White Dwarf.

What are the 7 stages of a low mass star?

Seven Main Stages of a Star

  • Giant Gas Cloud. A star originates from a large cloud of gas.
  • Protostar. When the gas particles in the molecular cloud run into each other, heat energy is produced.
  • T-Tauri Phase.
  • Main Sequence.
  • Red Giant.
  • The Fusion of Heavier Elements.
  • Supernovae and Planetary Nebulae.

How long do low mass stars live?

The smallest stars in the universe have exceedingly long lives — in fact, none have faced their end yet. Red dwarfs, stars with less than 0.4 solar masses, burn so slowly that they might live to 100 billion years old, much longer than the current age of the universe.

What are the 7 stages of a low-mass star?

How long do low-mass stars live?

What is the cycle of a high mass star?

The exact stages of evolutions are: Subgiant Branch (SGB) – hydrogen shell burning – outer layers swell. Red Giant Branch – helium ash core compresses – increased hydrogen shell burning. First Dredge Up – expanding atmosphere cools star – stirs carbon, nitrogen and oxygen upward – star heats up.

What is an example of a medium sized star?

Medium stars are those that, too big to end as white dwarfs and too small to become black holes, spend their dying years as neutron stars. Scientists have observed this category to have a lower limit of just above 1.4 solar masses and an upper limit in the neighborhood of 3.2 solar masses.

Do low mass stars live longer?

A smaller star has less fuel, but its rate of fusion is not as fast. Therefore, smaller stars live longer than larger stars because their rate of fuel consumption is not as rapid.

What happens when a star bigger than the Sun’s core collapses?

If the core is larger, it will collapse into a black hole. To turn into a neutron star, a star must start with about 7 to 20 times the mass of the Sun before the supernova. Only stars with more than 20 times the mass of the Sun will become black holes.
