What do we call a large family of millions of stars?
Red giants. By the way, what if it was a white star.
Which is a star in its old age Protostar Main sequence Black Hole or Red giant?
Red giant.
Is the big red giant Jupiter?
No. The Great Red Spot is a very large storm on Jupiter. A red giant is a type of star.
What is an expanding star after exhausting its hydrogen fuel called?
A Red Giant or a Red Super Giant if it is very large.
A large cool star formed when a star runs out of hydrogen?
red giant
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
Which types of star has low temperature and high luminosity?
A red giant star.
Is red giant a star or a type of star?
Red giant is a type of star.
What is the brightest star on the Gemini?
The brightest star in Gemini is Pollux, an orange giant star of magnitude 1.2
What color is the red giant that is in space?
A red giant star is a dying star that is in the last stages of stellar evolution. Red giant stars are red in color.
What is the brightest red giant?
Arcturus with an apparent magnitude of −0.04
What is the name of red giant star?
Its justa red giant or supergiant
What is a real example of a red giant star?
Betelgeuse is a red giant.
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.
Is the Dubhe star a red giant?
No, it is a Yellow Giant
What is the apparrent magnitude of the star Betelguese?
The apparent magnitude of Betegeuse is 0.5 and it has an M2 spectrum making it a red star. Its distance is 420 light years and its absolute magnitude is -4.5 so it is 9 magnitudes brighter than the Sun; that is 4000 times brighter, so it's a giant. It is slightly variable in its brightness. At the same distance the Sun would be a 9th magnitude star, invisible except in a telescope.
