Red giants. By the way, what if it was a white star.
They're elliptical shaped and the typically have a red center because of all the red giants that form in this type of galaxy.
it is called the photoflare
A star might begin to die after its main sequence. It'll balloon to a very big size. They're called red giants because the star is big and red. A red giant can die, though. Red giants die when their surface sheds into a cloud called a planetary nebula. Its core becomes a white dwarf. Our sun will go through this path.
Red Giants:)
All stars eventually turn into Red Giants or Super Giants
If they have red stars including giants in, they can't be all that featureless.
Yes red giants are the largest. But the bigger stars of red giants can be called red hyper giants.
red giants
binary star
Yes, there are. The classic red giants that come from sun- like stars, and red supergiants come from blue giants.
Generally red giants are bigger, but really it has more to do with how hot they burn. Blue giants burn hotter and have more mass.
Red Giants are 20 to 100 times bigger than the Sun.
The Doppler effect is well known, and Fizeau observed the red-shift of the light from distant stars. So the effect was called Doppler-Fizeau. There are a class of astronomic objects called the Cepheid Variables in which it is observed that the rate of variation in the brightness of the star related to its absolute brightness, and therefore its mass. Thus these stars can be used as a measure of distance, as the period of their variability does not change with distance, but their apparent brightness and their red-shift does. Hubble made a number of observations of Cepheids in the Andromeda galaxy. The article on Cepheid Variables in wikipedia.org is well worth reading, as it illustrates scientific discovery and enquiry. He went on to reason that the Cepheids could be used as a standard measure of astronomical distance. And this formed the basis of the Expanding Universe. These observations are one of the foundations of cosmology.
Well light wise the highest category would be blue giants, red giants, and super red giants.

White Dwarfs, Supergiants, and Red Giants are stars that are found in the sky.
