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.
Which are hotter white dwarfs or red giants?
red giants
How long do dwarf stars live?
How long stars live depends primarily on their mass. Low mass stars live longer.A yellow dwarf star like the Sun has an expected lifetime of about 10 billion years on the main sequence, followed by a "red giant" phase that is considerably shorter, followed by a "white dwarf" (Type VII) phase lasting a very, very, very long time before the star eventually cools to the point it no longer emits light in the visible range, becoming a "black dwarf".Low-mass red dwarfs (below, say, 0.25 stellar masses) could conceivably live trillions of years. We don't really know exactly what will happen to them or how long they will live, because the universe itself is only about 14 billion years old, not nearly long enough for any red dwarfs to have died.
Is a red giant the coldest star?
No. Red giants have temperatures comparable to those of red dwarfs. Even cooler are brown dwarfs, which are objects that are in the intermediate range between planets and stars.
Do red dwarfs and red giants have similar brightness?
no.they varry in brightness
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).
What is the percentage of stars in the universe are red dwarfs?
70-75% of stars are red dwarfs.
What stars are the oldest red dwarfs white dwarfs red stars or giant stars?
According to <studyisland.com>, white dwarfs are the oldest.
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.
How long will a black dwarf star live?
It is unknown. Scientists belive that, since the life length of white dwarfs are so long, there aren't any black dwarfs in our universe yet.
How long does the dwarfs frogs live?
3 - 10 years in good water conditions
Are red dwarfs bright?
Red dwarfs are not bright because they are not very luminous, they don't emit a lot of light.
Where are white dwarfs supeegiants and red giants?
White Dwarfs, Supergiants, and Red Giants are stars that are found in the sky.
How long do Netherland dwarf rabbits live until?
netherland dwarfs live up to 10 years but can live a lot longer if takegood care of
Do red dwarfs burn their fuel very slow?
Yes, red dwarfs burn their fuel slowly because they have small sizes.
What is the life expectancy of darwfism?
Both dwarfs and giants do not live very long compared to normal man.
Which are hotter white dwarfs or red giants?
red giants
