An old, very dense, hot star that is cooling is called a white dwarf. These stars are the remnants of medium-sized stars that have exhausted their nuclear fuel and shed their outer layers. Over time, they gradually cool and fade, eventually becoming faint stellar remnants known as black dwarfs, though the universe is not old enough for any black dwarfs to exist yet. White dwarfs are primarily composed of electron-degenerate matter, which accounts for their high density.
What else can I help you with?
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
Is a star's outer layer hot and dense?
Yes, a star's outer layer, called the photosphere, is hot and dense. This is where most of the visible light and heat emitted by the star originate. The temperature and density of the photosphere vary depending on the type and age of the star.
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.
Why is a neutron star called a neutron star?
A neutron star is a type of stellar remnant that results from the gravitational collapse of a massive star during a supernova.Such stars are composed almost entirely of neutrons, which are subatomic particles without electrical charge.See related link for more information.
When a very large star explodes it is called a?
supernova

What is the core of a star called if it is crushed in to a small but very dense object?
"Small but very dense" sounds like the description of a neutron star or "collapsed matter star". Theoretically, a black hole (the only thing more dense) has no physical size at all. So, "neutron star". If the neutron star is spinning rapidly, they are called "pulsars" for the radio-wave pulses that they generate.
What is the term for the very dense white dwarf star that is left behind after a supernova?
Neutron Star

What is a dense collapsed core with a very strong gravitional pull that forms when a very massive star become a supernova?
Neutron Star
What is the term for tiny very dense white dwarf star that is left behind a supernova?
Neutron Star
What is the term for the tiny very dense white dwarf star that is left behind a supernova?
Neutron Star
Will our sun end up like a neutron star?
No, our sun is not massive enough to become a neutron star. When our sun runs out of fuel, it will shed its outer layers and become a planetary nebula, leaving behind a dense core called a white dwarf.
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.
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 was the very very first Star Wars book of all called?
The very first book of Starwars was called "Star Wars: Rogue Planet"
