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.

What is an old dense hot star?
White dwarf
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).
Why the color of dwarf star is red?
Only a red dwarf star is red. Our Sun is a yellow dwarf. A red dwarf is red because it is cool, and cool colours are red whereas hot colours are white and blue.
What is the term for the tiny and very dense white dwarf star that is left behind after a supernova?
I think that's a pulsar.
What are some astronomical terms and their meanings?
A black hole is a collapsed star that does not let light escape. A nebula is a mass of gas and dust that may collapse to form a star. A red giant is a star that has expanded and cooled. A white dwarf is an old, dense, cool star.
What is a cooled white dwarf star that is extremely dense?
A cooled white dwarf is a black dwarf. I think you are thinking of a neutron star which has nothing to do with a white dwarf.
What star is An Old Dense Hot Star?
White dwarf
What is an old dense hot star?
White dwarf
Which is bigger a neutron star or a white dwarf?
A white dwarf is much larger than a neutron star.
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).
Are white dwarf stars always white?
No in the life cycle of a star, a white dwarf can cool and become a black dwarf
How can a star that has more mass than the sun be smaller than your sun?
The obvious reason is that the specific star has bigger density compared with the Sun. For example, that star could be a "white dwarf star". A white dwarf mostly contains "electron degenerate matter", which is very dense. A white dwarf is a small dense star.
What is the small dense remains of a high -mass star?
white dwarf
What is small dense remains of a high mass 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 the term for the very dense white dwarf star that is left behind after a supernova?
Neutron Star
What is the term for tiny very dense white dwarf star that is left behind a supernova?
Neutron Star
