What stars are the oldest red dwarfs white dwarfs red stars or giant stars?
The oldest stars are typically red dwarfs, which are small, cool, and faint stars that have long lifespans. White dwarfs are the remnant cores of low to medium mass stars, not the oldest. Giant stars are intermediate stage stars that have evolved away from the main sequence.
What do white dwarf stars become?
Black dwarfs. [See related question]
Are black dwarfs a solid liquid or a gas?
None of the above. White dwarfs and the black dwarfs they will become consist of a unique state of matter called electron degenerate matter.
Why have no white dwarfs cooled to form black dwarfs in the galaxy?
According to astronomers and authors Jonathan Weiner and Carl Sagan, white dwarfs - which have been an accepted entities by all astronomers for decades - require an amount of time to "cool down" that well exceeds the current age of the universe - hence there hasn't been enough time for any of them to cool down yet and become "black dwarfs".
What is the supernova of a red dwarf?
According to prevailing astronomical theory, red dwarfs do not become supernovae, so the best answer to the question is "nonexistant."
A dying star shrinks to this?
Dying stars eventually shrink into white dwarfs (which as they age eventually become red dwarfs and then brown dwarfs - but this takes an extremely long time).
Where are white dwarfs supeegiants and red giants?
White Dwarfs, Supergiants, and Red Giants are stars that are found in the sky.
Do stars die out after becoming white dwarfs?
No. Stars become white dwarfs after dying.
Very small stars that are usually old and running out fuel are called?
Those are dwarf stars, which start out as white dwarfs and as they (very slowly) cool, become red dwarfs and eventually brown dwarfs.
Which are hotter white dwarfs or red giants?
red giants
Are white dwarfs older then red giants?
yes they are
What stars are the oldest red dwarfs white dwarfs red stars or giant stars?
The oldest stars are typically red dwarfs, which are small, cool, and faint stars that have long lifespans. White dwarfs are the remnant cores of low to medium mass stars, not the oldest. Giant stars are intermediate stage stars that have evolved away from the main sequence.
Are giants hotter than white dwarfs?
No, white dwarfs are much hotter than giants. Giants are stars in the later stages of their evolution, while white dwarfs are the remnants of dead stars that have exhausted their nuclear fuel. White dwarfs can have surface temperatures in the tens of thousands of degrees Kelvin, while giants have lower surface temperatures.
What is the book that features Rose Red and Snow White?
Snow-White and Rose-Red, not to be confused with Snow White and the Seven Dwarfs
What do stars that have ejected a planetary nebula eventually become?
Stars that have ejected a planetary nebula eventually become white dwarfs. These are core remnants of low to medium mass stars that have exhausted their nuclear fuel. White dwarfs gradually cool down over billions of years to become black dwarfs.
Are white dwarfs older than the sun?
Some white dwarfs are older than the sun, and some are not. More massive red dwarfs form from stars larger than the sun, which do not last as long.
What is the diffrance between stars that become white dwarfs and stars that become neutron stars?
Stars that become white dwarfs die but become black holes . Neutron stars are born from a Super Nova that stored its energy and became a neutron star.
