It depends. The lower the mass of the star, the longer the lifespan. It is believed that the lifespan of these stars exceeds the expected 10 billion year lifespan of our Sun by the third or fourth power of the ratio of their masses to the solar mass, which means a red dwarf with 0.1 solar mass may continue burning for 10 trillion years

What is the next stage in the life of a lower-mass main-sequence star?
white dwarf. unless you count black dwarf of which none have been observed, only theorized.
What is type of star has an average life of 10 billion years?

What is the White Dwarf stars life cycle?
A white dwarf star starts out like a our sun and turns into a white dwarf at the end of the stars life cycle. They have used up all their nuclear energy. At the end of this nuclear burning stage the star expels most to all of its outer materials. This creates what is known as a planetary nebula. The hot core is the only part of the star that remains. Temperatures of the core can and will exceed 100,000 Celsius becoming a very hot white. From this point the star starts to cool down, but that takes a billion years or more.
Are white dwarf stars always white?
No in the life cycle of a star, a white dwarf can cool and become a black dwarf
The star that is the red and the cool?

How long is the Sun's life expectancy?
It should "live" for about 5 billion years as it is, more or less. Then it will become a red giant star. Then it becomes a white dwarf. Finally it will "die" as a black dwarf.
Steps in the life of a star?
the steps in the life of a star is the yellow dwarf,red giant,white dwarf & the black dwarf.
Why the color of dwarf star is red?

What is the name of the cool red star?
red dwarf i think!
If a star was 150 solar masses what would its lifetime be?
A star that was 150 solar masses would spend the main part of its life as a main sequence star before collapsing into a white dwarf. A stars mass determines the life expectancy as well as its probable cause of death.
What is a small star that only gives of faint light and are cool?
That can either be an old white dwarf, a red dwarf. or a brown dwarf.
What do you call a small faint relatively cool star?
If it is small and cool enough it could be a "brown dwarf". If it is a little warmer it is called a "Red Dwarf".
What is another name for a small old cool star?
white dwarf
Star of life?
Nebule > Star > Red Giant > Red Dwarf > White Dwarf > Supernova > Neutron Star > Black Hole.
Is a white dwarf an old dense cool star?
A white dwarf is the remains of an old star, but they still remain very hot and will continue to shine as a white dwarf for many millions of years until they gradually cool off to become black dwarfs. They are very dense.
