Algol or the Demon star is a star in the constellation Perseus.
It has an apparent magnitude (as seen from Earth) of 2.12 or an absolute magnitude of -0.15.

The absolute magnitude is -7.92
-6.02
A star's brightness at a standard distance is referred to as its apparent magnitude. This standard distance is 10 parsecs (32.6 light-years) from Earth. Apparent magnitude allows astronomers to compare the brightness of stars as seen from Earth, regardless of their actual distance from us.
Brightness of stars (apparent and absolute magnitude) is measured by convention, taking an another star as a standard.
Algol, also known as Beta Persei, is a binary star system with a surface temperature of approximately 7,500 Kelvin for its primary star. This temperature gives it a bluish-white color in the visible spectrum. The secondary star in the system is cooler, with a surface temperature around 5,000 Kelvin, resulting in a yellowish hue. Overall, Algol is known for its significant brightness and variability.

The variable of distance is eliminated when discussing absolute brightness. Absolute brightness specifically refers to the inherent brightness of an astronomical object without the influence of its distance from the observer.
A fixed star, in Medusa's head, in the constellation Perseus, remarkable for its periodic variation in brightness.
If you mean infinite brightness, then nothing.

Algol is a binary star system composed of two stars orbiting each other. The dimming and brightening of Algol occur when the dimmer star passes in front of the brighter star from our point of view, resulting in an eclipse. This regular change in brightness is known as an eclipsing binary system.
A star's brightness at a standard distance is referred to as its apparent magnitude. This standard distance is 10 parsecs (32.6 light-years) from Earth. Apparent magnitude allows astronomers to compare the brightness of stars as seen from Earth, regardless of their actual distance from us.
Anything that is not the measure of intrinsic brightness of a celestial object.
Absolute Brightness: How bright a star appears at a certain distance. Apparent Brightness: The brightness of a star as seen from Earth.
