Both white dwarfs and neutron stars match the description. Neutron stars are smaller, hotter, and denser.
What else can I help you with?
What kind of star is hot and has a very small radius?
A white dwarf star fits this description. White dwarfs are hot due to residual heat from their earlier stellar evolution, but they have a small radius comparable to that of a planet like Earth.
What is an older star that has become small?
An older star that has become small is called a white dwarf. White dwarfs are the remnants of low to medium mass stars that have exhausted their nuclear fuel and collapsed to a very dense state. They are very hot and small compared to their original size as a main sequence star.
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.
Is the white dwarf a large star that is relatively cool?
No it is a small star (about the size of Earth) that is VERY dense and quite hot (although it is not producing new energy).
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 star is very hot but gives off little light?
Answer: A shooting star Answer: One with a small surface, such as a white dwarf or a neutron star. These are "dead stars", in the sense that energy production has stopped.
What star is very small?
dwarf star
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.
What do you call a tiny and very hot star?
It is called a neutron star.
The birth of a small star and a very massive star are the same but the end of their life is very different Describe the difference in the fate of a small star and a very massive star?
The difference between the death of a small star and a massive star is what the become afterwards. A small star will typically become a red dwarf while a large star will become a neutron star or a black hole.
What is one fact about a star?
They are 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).
