As the name white dwarf implies, this is a small type of star, and it has less surface area from which to radiate light, so even if it is hot, and giving off lots of light per square mile, there are fewer square miles than in larger, non-dwarf stars, so there is less total light being emitted.
What else can I help you with?
Why are dwarf plants are hot but dim?
I assume you mean a DWARF STAR. There are different types of dwarf stars; the white dwarfs are fairly hot - but the reason they are dim is that they have a very small surface area.
Is a White Dwarf so hot it takes billions of years to cool?
Yes, white dwarfs are extremely hot when they first form but over billions of years they gradually cool and dim as they release their leftover thermal energy into space. This cooling process is what eventually transforms them into cold, dark celestial objects known as black dwarfs.
A star that is very hot but dim is a?
That might be a white dwarf.
Which category of stars is extremely hot and dim?
White dwarves.
Why no red dwarfs have become white dwarfs?
Red dwarfs have not yet evolved into white dwarfs because red dwarfs are much less massive than other types of stars that do become white dwarfs. Red dwarfs are the smallest and coolest stars, and they have not burned through their fuel quickly enough to go through the stage of becoming a white dwarf. It will take billions of years for a red dwarf to cool and fade into a white dwarf.

What types of stars are dim and hot?
There could be many answers as dim and hot are mutually exclusiveBrightness (or dimness for that matter) is defined as a stars luminosity and it's distance from the observer.So a hot star could be very far away and appear dim, whereas if it was relatively close, it would appear bright.A hot but small star, would appear dim at a close distance.However, in all likelihood the answer you might be looking for is either:Neutron Star - Very small and very hotWhite Dwarf - Small and very hot
What is an example of a hot star which is not very bright?
This could be a white dwarf. Its essentially a `dead star` as nuclear reactions no longer take place, but it remains very hot for millions of years from residue heat. They are very small though, compared with other stars or the size they used to be. If a hot bright star is very very far from earth then this also will appear dim from earth. It may have a low apparent magnitude (but a high absolute magnitude).
How white dwarf stars can be both hot and dim?
White Dwarf Stars are very hot, like a ball of fire. They are dim because they are small and very far away.
What is A small hot dim star that is the left over center of an old star?
This describes a white dwarf, which is a small, dense star that remains after a star has exhausted its nuclear fuel and shed its outer layers. White dwarfs emit heat and light as they slowly cool down over billions of years.
Why is the white dwarfs white?
They are called white dwarfs because when they form, although not replenishing their energy supply any more, they are still hot enough to shine. Overt time (a long time) however, they will cool down and become 'black dwarfs' which no longer emit light in visible wavelengths.
