What is an old star of average size that has begun to expand and cool as its fuel has begun to run out?
Red giant.
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.
What is an old dense hot star?
White dwarf
How old is a yellow star?
It can be as old as 10 billion years. Then it increases to the size of a giant and supernova. After that it turns into a small dense white dwarf.
What happens when the outward force of pressure wins out over gravity in an old star?
When the outward force of pressure wins over gravity in an old star, the star will expand and cool, becoming a red giant. This process occurs as the star exhausts its nuclear fuel and transitions to a different phase of stellar evolution.
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 red giant an old very dense hot star that is cooling?
No, a red giant is not an old, very dense hot star that is cooling. Instead, it is a late stage in the evolution of a star that has exhausted the hydrogen in its core and is now fusing helium or heavier elements. As a result, the outer layers expand and cool, giving the star its characteristic reddish color. While red giants can be quite large, they are not notably dense compared to other stellar types, like white dwarfs.

What is the differences between a red dwarf and a red giant star?
Well first of all the SUN is alive -orbits around planets - Medium sized - gives out heat Red Giant Not alive -floats around space -giant siZed -cool - fl
What happens when the outward force of pressure wins out over gravity in an old star?
When the outward force of pressure wins over gravity in an old star, the star will expand and cool, becoming a red giant. This process occurs as the star exhausts its nuclear fuel and transitions to a different phase of stellar evolution.
Which is a star in its old age Protostar Main sequence Black Hole or Red giant?
A red giant is a star in its old age. During this stage, a star expands and cools as it exhausts its hydrogen fuel. Eventually, it will shed its outer layers, forming a planetary nebula.
How many stars in giant elliptical?
Giant elliptical galaxies typically contain a vast number of stars, often ranging from several hundred billion to over a trillion stars. Their star populations are mostly old, with little new star formation, resulting in a dense and tightly packed structure. The exact number can vary significantly depending on the specific galaxy in question.
