Red dwarves have very low mass, less than 40% of that of our own sun. As a result, they have relatively low temperatures in their cores such that energy is generated at a very slow rate through hydrugen fusion into helium. Very little light is emitted, even the largest red dwarf emits less than 10% of that of our sun.
The biggest difference between a red dwarf and our own sun is the total absence of a metallic core.

Mostly hydrogen, like any other star which is still burning.
wierd shut up
All stars are "mostly hydrogen, with some helium". Most stars have traces of heavier elements, and the exact proportion is different for every star and every stage of the star's life. When stars get large proportions of heavier elements, they are near the end of their lives.
What else can I help you with?
Why would a white dwarf become a red dwarf?
A white dwarf could not become a red dwarf. A white dwarf is a remnant of a dead star. A red dwarf is a star with a very low mass.
What type of star has low mass low temperature and low absolute magnitube?
A red dwarf.
Where does most of the mass of red giant go when the star becomes a white dwarf?
When a red giant evolves into a white dwarf, most of its mass is lost during the outer envelope's expulsion, which occurs in the form of stellar winds and planetary nebulae. The core, which remains, is primarily composed of carbon and oxygen and is what ultimately forms the white dwarf. This process significantly reduces the star's mass, with only the dense core remaining as the white dwarf.
What color is a low mass star?
A low mass star typically appears red in color due to its cooler surface temperature. This type of star is classified as a red dwarf and emits a reddish light compared to higher mass stars.
How much mass does Proxima Centauri have?
It's a red dwarf, so its lower limit is around 0.008 solar mass.
Why would a white dwarf become a red dwarf?
A white dwarf could not become a red dwarf. A white dwarf is a remnant of a dead star. A red dwarf is a star with a very low mass.
What conditions will exist in a star that has turned into a red dwarf?
A star does not turn into a red dwarf. A red dwarf is simply a star that has a low mass to begin with.
Is a white dwarf older the a red dwarf?
Not necessarily. A white dwarf is simply the remains of a low to medium mass star that has died. A red dwarf is a low mass star. Since red dwarfs last longer than medium mass stars, one could easily be older than a white dwarf.
Is a white dwarf smaller than a red dwarf?
Yes, far smaller. A red dwarf is a whole star in and of itself. A white dwarf is the collapsed remnant of the core of a low-to medium mass star. A white dwarf may be about the size of Earth.
What is a low mass star (main sequence)?
A star with a low mass will go through these stages: 1. Protostar nebula 2. Main sequence (as a red dwarf) 3. Red giant 4. Planetary nebula 5. White dwarf (6. Black dwarf is theorized to occur after white dwarf)
What is the size of a dwarf star?
Several times smaller than our Sun. Details vary, depending on the type of dwarf star (a red dwarf and a white dwarf are quite different things), and the exact mass.
How many Red Dwarf stars do astronomers estimate have burnt out since the beginning of the universe?
Basically, none. Red dwarf stars have a lifetime that is much larger than the age of the Universe.Actually, if a lot of additional mass falls on a red dwarf star, it would start to burn more quickly. But then, of course, it would no longer be a red dwarf star.
What color is Barnards star?
Barnard's Star is a very low-mass red dwarf star and has a spectral type of M4V.So it has the colour red.
What type of star has low mass low temperature and low absolute magnitube?
A red dwarf.
Is a red dwarf star made from a supernova?
No, red dwarf stars are not made from supernovae. Red dwarf stars are low mass stars that form from the gravitational collapse of gas and dust in interstellar clouds. Supernovae, on the other hand, occur when massive stars reach the end of their life cycle and explode.
What are the three classification of star?
Red dwarf, yellow dwarf, red dwarf
How much bigger is the sun than the smallest star?
The mass of a red dwarf can go down to about 0.075 times the mass of the Sun. Anything smaller than that would be a brown dwarf, which is no longer considered a star.
