What do we call a large family of millions of stars?
Red giants. By the way, what if it was a white star.
What is the magnitude dubhe?
Dubhe, a star in the Big Dipper asterism, has an apparent magnitude of approximately 1.81. It is a red giant star located about 124 light-years from Earth and is one of the brightest stars in the constellation Ursa Major. Its relatively high brightness makes it easily visible to the naked eye.
A large cool star formed when a star runs out of hydrogen?
red giant
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.
What is an expanding star after exhausting its hydrogen fuel called?
An expanding star after exhausting its hydrogen fuel is called a red giant. This stage occurs when the core contracts and heats up, causing the outer layers of the star to expand and cool, giving it a red color.
What is the average temperature drop when a star turns into a red giant?
When a star turns into a red giant it means the force of the frequency is lighted by the sun. And then when calculating the magnitude it takes time and days for the sun to orbit

Betelgeuse is a red giant.
What is the name of red giant star?
Its justa red giant or supergiant
What is the brightest red giant?
Arcturus with an apparent magnitude of −0.04
What happens to the magnitude of a star in the main sequence as its temperature decreases?
The cooler a star is, the less luminous it is. That's assuming the star stays about the same size. "Red giant" stars for example are relatively cool, but very luminous because of their size. However, red giants are not main sequence stars. For a main sequence star, a lower temperature means it is LESS bright. That means it has a higher number on the "magnitude" scale. So the answer is: "the magnitude increases" Our Sun is putting out more energy than it did a billion years ago. It is expected to get even hotter before it leaves the main sequence and becomes a red giant.
What do we call a large family of millions of stars?
Red giants. By the way, what if it was a white star.
Is the Dubhe star a red giant?
Dubhe is not a red giant but rather a subgiant star. It is the brightest star in the Big Dipper asterism and is classified as an evolved F-type subgiant star.
