Transcript of Dwarf Stars

Many types
Dwarf Stars
Believed to be the final stage of stellar evolution.
Remaining part is the carbon core
Luminosity continues to decrease
White dwarf
Red Dwarf Stars
Red Dwarf to White then Black
Low mass main-sequence stars
Longest living Dwarf Star
Orange Dwarf Star
Turns into a white dwarf
K-type main sequence star
Best habitual zones
Yellow Dwarf
Our sun is a yellow dwarf
It will eventually turn into a white dwarf
The estimated time for our sun to cool enough to become a black dwarf is 1 quadrillion years
Blue Dwarfs
Very rare
Starts as a red then turns into a Blue
Increase in temperature as they reach the end of their lifetime
Brown Dwarf
Not a planet, not an ordinary star
Forms just as normal stars except the protostar is not massive or dense enough to sustain hydrogen fusion
Becomes a "Failed Star"
Orange Dwarf
Red Dwarf
Orange Dwarf
Red Dwarf
Black Dwarf
Theoretical final stage of stellar evolution
The time for a black dwarf to exist is older then the age of the universe
If they were to exist they would be very difficult to locate because they emit no heat or light
