Mizar is a quadruplet system of two binary stars in the constellation Ursa Major.All stars are type A which means they are about twice as big as our Sun and about twice as hot. The stars will appear white in colour.
Mizar is a quadruple or quaternary star system. When there is more than two stars, it is called a star system or multiple star system or stellar system. Depending on the number of stars, they are also called a triple, quadruple or quintuple star system or trinary, ternary, quaternary, quintenary, sextuple, sextenary, septuple or septenary star system.
The Alcor star which resides in URSA MAJOR, part of the star that makes up the big Dipper, is 81 light years from earth. FYI: Alcor and Mizar are twin stars or double stars which almost line up directly behind each other. However, Alcor is behind Mizar but resides slightly above and to the left of Mizar.

how can a red giant star become brighter if it now has a lower surface temp
Eta Carinae, with a mass 180 times that of the sun has a surface temperature of around 40,000 K. It is the hottest known star.
