An expanded star is a star that has reached later stages of its life cycle where it has increased in size and luminosity. This expansion is typically caused by changes in the star's core, leading to the outer layers swelling up. Examples of expanded stars include red giants and supergiants.

Which is denser a dwarf star or a giant star?
A dwarf star is denser than a giant star. Dwarf stars have a higher density due to their smaller size and higher mass compared to giant stars. Giant stars have larger volumes and lower densities as they have expanded and become less dense towards the end of their life cycle.
What type of star is caph in the constellation cassiopeia?
Caph, also known as Beta Cassiopeiae, is a yellow-white giant star located in the constellation Cassiopeia. It is about five times the size of the Sun and is at a stage of its evolution where it has expanded and cooled from its main sequence phase.
What type of star is torcular?
Torcular is a type of Mira variable star that exhibits pulsations and periodic changes in brightness. These stars are red giants that have expanded and are nearing the end of their life cycle, with their outer layers becoming unstable and pulsating.
How did Betelgeuse get so big?
Betelgeuse is very big because is formed as a large star, and later it expanded even more as it ages, this creates its current size.
Which is the correct order - white dwarf or red?
The correct order is red giant followed by white dwarf. A red giant is a stage in the life cycle of a star where it has expanded and cooled. After the red giant phase, the star sheds its outer layers and the core collapses to form a white dwarf.
What is a star that expanded and cooled?
Such a star is called a red giant.
Is a black hole an expanded star?
No. A black hole can be a very condensed star. It's also possible for "mini" black holes of less than stellar mass to exist. But in no case would it be possible to describe one as an "expanded" star.
How many movies was made of star wars?
6, and then there was an animated expanded universe movie.
What series has more characters Star Wars or Halo?
Probably Star Wars, as you have the films, animated series, expanded universe books to factor in.
What series has more characters-Star Wars or Halo?
Probably Star Wars, as you have the films, animated series, expanded universe books to factor in.
How many Darth's are there in the Star Wars universe?
4 i think in the movies. In the expanded universe there are many more.
Is aldebaran a giant star?
Yes, it is an orange giant star. It is an old star which has ran out of hydrogen fuel and has moved off the main sequence, having expanded to around 44 times the diameter of our own sun.
A star that has expanded and cooled is what?
A star that has undergone expansion, deflation and cooling is known as a white dwarf, or degenerate dwarf. It is a small star made up of mainly electron-degenerate matter.
What is the difference between a red giant and a neutron star?
A red giant is a star in the final stages of its life time that has expanded to hundreds of times its original diameter. Because the star has expanded without gaining mass, a reg giant has an extremely low average density. A neutron star is the collapsed core of a dead massive star. It contains a mass a few times that of the sun in an area only a few miles across, making it extremely dense; only the singularity of a black hole is denser.
A giant star is always what?
A giant star is always larger and more massive than our sun. It is in a later stage of its life cycle where it has exhausted its core hydrogen fuel and has expanded.
What are some astronomical terms and their meanings?
Supernova: the explosion of a star that results in a sudden, extreme increase in brightness. Black hole: a region of spacetime where gravity is so strong that nothing, not even light, can escape its pull. Nebula: a cloud of gas and dust in space, often the birthplace of new stars. Galaxy: a large system of stars, gas, dust, and dark matter bound together by gravity.
How are giant stars and white dwarf related?
A giant star is a dying star that expanded, and the core shrinks are the same time. When the shell of the giant star drift into space as planetary nebula, the core became a white dwarf. The white dwarf is made from the core of the giant star.
