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.
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).
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.
What happens when a massive star cools and collapses?
Massive stars do not cool as they collapse, the collapse in on themselves because their cores become too heavy and dense, these atoms in the core are in an area so dense and so hot that it continues to increase its temperature as it explodes.
What type of star is the leftover center of an old star?
The leftover center of an old star can become either a white dwarf, neutron star, or black hole, depending on its original mass. A white dwarf forms from stars like our Sun, where the outer layers are shed, leaving a hot core that gradually cools. Neutron stars arise from more massive stars that undergo supernova explosions, resulting in a dense core primarily composed of neutrons. If the original star is sufficiently massive, it can collapse into a black hole after its supernova phase.
What star 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.
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.
What is an old very dense hot star that is cooling called?
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.
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).

Does a main sequence star maintain a stable size?
After a star has formed, it creates energy at the hot, dense core region through the nuclear fusion of hydrogen atoms into helium.
What fundamental forces pulled together hot dense areas of matter in the early Universe to begin the process of star formation?
gravity
Is the air on a hot humid day less dense or more dense than on a hot dry day?
it is less dense
What is a dense rapidly spinning star?
Studying star and star types can be fun, but it can be challenging to remember each type. A Neuron star is a dense, rapidly spinning star.
