Dwarf stars are NOT "so much Bright", the smaller the star is (provided it is on the main sequence) the less intrinsically bright it is.
What else can I help you with?
Are white dwarf stars very bright or faint compared to regular stars?
Answer #1: bright===================Answer #2: They're faint.Another answer: They are indeed very faint.They can have high surface temperatures, but they have very small surface areas.No white dwarf star is visible from Earth with the "naked eye".
What the relationship between magnitude and size of the star?
The brightness of a star depends on its temperature, size and distance from the earth. The measure of a star's brightness is called its magnitude. Bright stars are first magnitude stars. Second magnitude stars are dimmer. The larger the magnitude number, the dimmer is the star.The magnitude of stars may be apparent or absolute.
Why is the sun a dwarf star?
A yellow dwarf star, is a star on the main sequence that has a temperature range of between 5,200 to 6,000 Kelvin. It has a spectral class of G or possibly F.Our Sun is a yellow dwarf - much as you may not believe it, it is a dwarf compared to other stars!!See related question for a size comparison
How many Red Dwarf Stars are there in the Milky Way Galaxy that we know of in October of 2011?
The Milky Way has somewhere between 100 and 400 billion stars; most of those are red dwarf stars.
Why do you think there are so few dwarf stars among the twenty with the highest apparent brightness?
Probably because they are the closet to us!
Why are dwarf stars so much Bright?
Dwarf stars are NOT "so much Bright", the smaller the star is (provided it is on the main sequence) the less intrinsically bright it is.
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.
What group of stars is very hot but not very bright?
White Dwarf Stars.
How much power does a star in your galaxy have?
Every star is different. Some stars are millions of times brighter than our Sun, while some stars are so small that they barely glow at all. We can easily see the big, bright stars - but we have no idea how many tiny "red dwarf" or "brown dwarf" stars there might be. They are so dim, that we cannot see them from so far away.
Do Dwarf galaxies contain only dwarf stars?
Dwarf galaxies merely refer to the size of the galaxy itself, not the stars in the galaxy, so no.
What group of stars are bright but not hot?
White dwarf stars are bright due to their compact nature, but they are not hot in terms of surface temperature compared to other types of stars. They are "dead" stars that have exhausted their nuclear fuel and are slowly cooling off over time.
Are white dwarf stars very bright or faint compared to regular stars?
Answer #1: bright===================Answer #2: They're faint.Another answer: They are indeed very faint.They can have high surface temperatures, but they have very small surface areas.No white dwarf star is visible from Earth with the "naked eye".
Which are the two stars closest to earth after the sun and how bright are they?
Proxima centauri and Alpha centauri A and B. Proxima is less bright since it's a red dwarf but still detectable. These stars are in a triplet system.
What stars are cool stars?
Red Dwarf stars. Brown Dwarfs are failed stars, so they don't count.
Can you give an example of a hot star which is not very bright?
A white dwarf star can be very hot due to residual heat from its earlier evolution, but it may not be very bright because of its small size. This is because the heat energy is spread over a smaller surface area compared to larger, brighter stars.
What happens to a nova star after it becomes so bright?
after a nova star becomes bright it turns into a dwarf and explodes.
Are dwarf stars black holes?
no, dwarf stars don't have enough mass
