Low mass stars
What is steller equilibruim?
steller equilibrium is where the gravity pulling the star together and the energy pushing the star out is equal.
What is solar mass?
Solar mass is how big the sun is, so if a star has a solar mass of three, it is three times the size of the sun.

What is a low mass star
contains the letters dgrentia
what is a red giant
What elements do low-mass stars contain?
Low mass stars contain mostly hydrogyn and helium.
What elements do high mass stars contain?
High mass stars contain mostly hydrogen and helium.
What elements do red giants contain?
The main element in a red giant is helium, but there are trace amounts of carbon and oxygen as well.
What elements are in a white dwarf?
The main elements are helium and small amounts of carbon.
How are low-mass stars formed?
Low mass stars are formed when a steller nebula gets pulled together due to accretion and becomes hot enough to fuse hydrogen into helium. They must be under eight solar masses.
How are high mass stars formed?
High mass stars form when a steller nebula gets pulled together due to accretion and creates a giant star that can fuse hydrogen into helium. Their solar mass must be greater then eight to be a high mass star
How are red giants formed?
red giants form when a low mass star expands and starts to cool down, resulting in energy loss.
How do white dwarfs form?
White dwarfs form when a planetary nebula gets pulled together due to accretion and forms a white dwarf. They form because red giants cannot output enough energy to deal with the gravity and it eventually collapses.
What is a low mass star?
a low mass star is a star that can use chemical processes to turn hydrogen into helium.
What is a high-mass star?
What is a red giant?
A red giant is an expanded, cooled star with a low surface temperature. that reaches steller equilibrium for a short period before succumbing to gravity and collapsing into a white dwarf
What is a white dwarf?
A white dwarf is the remnants of a planetary nebula. it is very dense, and over time it will stop glowing and become a black dwarf. Fusion cannot happen in this star, because it is not hot enough (ten million degrees kelvin).
What processes occur within a low-mass star?
The main process in a low-mass star is the fusion of hydrogen into helium, which creates energy and keeps the star alive.
What processes occur within a high-mass star?
The main process in a high-mass star is the fusion of hydrogen into helium.
What processes occur within a red giant?
There is hydrogen fusion happening as the star is expanding, and eventually it will only fuse hydrogen on its outer layers
What processes occur in a white dwarf?
There are no main processes occurring in a white dwarf, except for cooling
