Stars near red in color are far cooler than ones which are bluish (considered as the hottest).
However the total output of a red giant star is very high even though its surface is relatively cool. This is because it has a large surface area.
If it is small and cool enough it could be a "brown dwarf". If it is a little warmer it is called a "Red Dwarf".
Betelgeuse is a red supergiant star located in the constellation Orion. It is a very luminous and relatively cool star, with a surface temperature of around 3,500 Kelvin.
Nahn is a red dwarf star, which is a small, relatively cool star that emits a red light. These stars are the most common type of star in the universe.
No it is a small star (about the size of Earth) that is VERY dense and quite hot (although it is not producing new energy).
The star FuruD is classified as a red giant, so it appears reddish in color. This is because of its relatively cool surface temperature compared to other stars.

Luminosity is related to temperature and distance.A cool and thus less luminous star would be brighter than a more luminous star at a greater distance.Our Sun is a relatively cool star in comparison to say Rigel, but because it is closer it appears more luminous and brighter.
cool
It is a cool star.
Barnard's star is a red dwarf, M-type main sequence star.
run them under cool water
When a star burns up all of its hydrogen,it becomes red in color.As hydrogen is the fuel for star and it will burst after it.
