How can a red giant become brighter if it now has a lower surface temperature?
how can a red giant star become brighter if it now has a lower surface temp
What color star has the highest surface temperature?
Red stars have the coolest surface temperature. Blue color stars have the highest surface temperature. The Sun belongs to the main sequence stars.
Which types of star has low temperature and high luminosity?
A red giant star.
Which color star has the lowest surface temperature?
Red
What are some surface features on Betelgeuse?
Betelgeuse is a red giant therefore its surface is of red color with some white sun spots.

What color star has the highest surface temperature?
Red stars have the coolest surface temperature. Blue color stars have the highest surface temperature. The Sun belongs to the main sequence stars.
Is a red super-giant hot?
The colour of a star is a good measure of the surface temperature.
How hot is the great red sun?
According to Wikipedia, a red giant has a surface temperature of 5000 K or less.
What is revealed by the red color of the super giant star called Betelgeuse's?
A red color, in a star, is associated with a low surface temperature.
Why will the color of the sun change from yellow to red when it becomes giant?
Color is related to surface temperature, and a "red giant" is cooler than a main sequence, medium-sized star like the Sun.

Which types of star has low temperature and high luminosity?
A red giant star.
Will a super red giant live longer than a red giant star and which will burn hotter?
A supergiant is brighter than a red giant. That means it spends its energy faster, and lives less. To burn its energy faster, it must be hotter in its nucleus. That doesn't necessarily mean that its surface temperature is faster (rather, it will usually be bigger, and have a larger surface to irradiate).
What is the temperature of a red giant?
It depends on how old it is
Will the suns temperature increase or decrease if the sun turns into a red giant?
The core temperature will increase, GREATLY. The surface temperature probably won't change all that much. And it isn't a case of "if", but of "when"; the Sun WILL turn into a red giant, in about 4 billion years or so.
What is the giant star?
The largest stars - that is, largest in diameter - are usually red. This is related to the fact that their surface temperature is relatively low. They still radiate huge amounts of energy though, due to their large surface.
