Both white dwarfs and neutron stars match the description. Neutron stars are smaller, hotter, and denser.

Is a star's outer layer hot and dense?
Yes it is! Just like the sun. Its Corona is very hot.
What kind of star is hot and has a very small radius?
north star
Match each body to its best description A. black hole an old very dense hot star that is cooling B. red giant a large star that is relatively cool C. white dwarf a an object so dense that even light c?
Black hole- an object so dense that even light cannot escape its gravity Red Giant - a large star that is relatively cool White Dwarf - an old, very dense hot star that is cooling Nebula - A mass if gas and dust
Can you give an example of a hot star which is not very bright?
White dwarf stars are hot , but not very bright, because they are so small. An example is "Sirius B", the companion of "Sirius A", the brightest star in the sky.
What kind of star is most likely to become a white-dwarf supernova?
A supernova is a star that has exploded into dust and gas. A white-dwarf is a small, hot, dense star nearing the end of its life, that did not have enough mass to go supernova. So the answer is "none".
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).
Is a star's outer layer hot and dense?
Yes it is! Just like the sun. Its Corona is very hot.
What kind of star is hot and has a very small radius?
north star
What star is An Old Dense Hot Star?
White dwarf
What is an old dense hot star?
White dwarf
Match each body to its best description A. black hole an old very dense hot star that is cooling B. red giant a large star that is relatively cool C. white dwarf a an object so dense that even light c?
Black hole- an object so dense that even light cannot escape its gravity Red Giant - a large star that is relatively cool White Dwarf - an old, very dense hot star that is cooling Nebula - A mass if gas and dust
What is a star that is dense and made up of hot gases?
the sun
Is a white dwarf an old dense cool star?
A white dwarf is the remains of an old star, but they still remain very hot and will continue to shine as a white dwarf for many millions of years until they gradually cool off to become black dwarfs. They are very dense.
Can you give an example of a hot star which is not very bright?
White dwarf stars are hot , but not very bright, because they are so small. An example is "Sirius B", the companion of "Sirius A", the brightest star in the sky.
What is the inner layer made of?
very dense and hot
Would the sun be hotter if it was bigger?
no, and this is very strange. the bigger the star the cooler it is! the smallest and hottest stars are dwarf stars! a lot smaller than our sun, these small stars are too hot and too dense to support life. hope this is helpful :)
What kind of star is most likely to become a white-dwarf supernova?
A supernova is a star that has exploded into dust and gas. A white-dwarf is a small, hot, dense star nearing the end of its life, that did not have enough mass to go supernova. So the answer is "none".
