What else can I help you with?
Are any of the 20 nearest or 20 brightest stars white dwarf?
Yes, some of the 20 nearest stars are white dwarfs. For example, Sirius B, the companion star to Sirius A, is a white dwarf. Among the 20 brightest stars, Sirius B is the only white dwarf.
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 dwarfs and neutron stars have in common?
Both white dwarfs and neutron stars are extremely dense remnants of the collapsed cores of dead stars.
What is more common in our galaxy white dwarfs or stellar mass black holes?
There are more white dwarfs. Only the most massive stars can form black holes. White dwarfs form from low to medium mass stars, which far outnumber the supermassive ones.
Are there more white dwarfs of more black holes?
I think white dwarfs. This is because they are much more low mass than black holes. White dwarfs are much more common in the universe than black holes, because we have only discovered a few black holes whereas we are aware of many white dwarfs.
Are the brightest stars white dwarfs?
No. White dwarfs are fairly dim. The brightest known stars are generally Wolf-Rayet stars.
Are any of the 20 nearest or 20 brightest stars white dwarf?
Yes, some of the 20 nearest stars are white dwarfs. For example, Sirius B, the companion star to Sirius A, is a white dwarf. Among the 20 brightest stars, Sirius B is the only white dwarf.
Do stars die out after becoming white dwarfs?
No. Stars become white dwarfs after dying.
Are stars blue in colour?
Stars vary in color and may be red, orange, yellow, white, or blue. Blue stars are the hottest and among the brightest.
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.
Do all stars begin as white dwarfs?
No. Stars do not start as whit dwarfs. A white dwarf is the remnant of dead star.
What do white dwarfs and neutron stars have in common?
Both white dwarfs and neutron stars are extremely dense remnants of the collapsed cores of dead stars.
Why are white dwarfs common?
White dwarfs are the remnants of dead low to medium mass stars, which is the mass range of the majority of stars.
Why are thre so many dwarf stars - red and white - among the nearest stars but none among the brightest stars?
Because dwarf stars aren't very bright. They are too SMALL to be especially bright, for one thing.
Is white dwarf a star?
Many stars are white dwarfs.
Are the hottest stars the brightest?
blue and white
Are white dwarfs alive or dead?
White dwarfs are stellar remnants, so it a simplified form, they are dead stars.
