What are the stages of a 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 stages of life for a low mass star quizlet?
- Star Forming Nebula.
- Nuclear Fusion Begins, Protostar.
- Core Pressure Balances Gravity, Main Sequence Star aka adult.
- Fuel Runs Out, Forces Unbalanced, Red Giant.
- White Dwarf with a planetary nebula (nothing to do with planets)

What happens when a low mass star?
Low mass stars use up their hydrogen fuel very slowly and consequently have long lives. Low mass stars simply die by burning up their fuel to leave behind white dwarfs (contracted low mass stars about the size of the Earth) which themselves cool and contract further to black dwarfs.
Why do younger stars have more heavy elements?
Why do younger stars have heavier elements than old stars? Because young stars are formed from the explosions of other stars , and those stars build up layers over time and have these heavy elements in them. So when they explode, you mainly have those heavy elements in molecular clouds for stars to form out of those.
Which 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 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 is the lowest mass star?
The classic low-mass star is the Sun . Low-mass stars have large convection zones when compared to intermediate- and high-mass stars. In very low-mass stars , the Convection Zone goes all the way to the star’s core! Over time, a low-mass star consumes all of the hydrogen in its core – what happens now?
What are the three end stages of star?
- White Dwarf.
- Neutrons Star.
- Black Hole.
What happens to a star at the end of its life?
Most stars take millions of years to die. When a star like the Sun has burned all of its hydrogen fuel, it expands to become a red giant. ... After puffing off its outer layers, the star collapses to form a very dense white dwarf .
What are the 5 stages of a star?
- A nebula. A star forms from massive clouds of dust and gas in space, also known as a nebula.
- Protostar. As the mass falls together it gets hot.
- Main sequence star.
- Red giant star.
- White dwarf.
- Supernova.
- Neutron star or black hole.
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 is the most massive star in the universe?
R136a1 . The star R136a1 currently holds the record as the most massive star known to exist in the universe. It’s more than 265 times the mass of our Sun, more than double most stars on this list. Astronomers are still trying to understand how the star can even exist.
What are remnants of low mass stars?
Supergiants: rare, high mass stars which have burned through their hydrogen and moved off of the Main Sequence. White Dwarfs : the remnants of low mass (less than ten solar masses) stars which have burned out completely. These are hot, but small, cores of former stars.
