This page provides all possible meanings and translations of the word ALGOL
the second brightest star in Perseus; the first known eclipsing binary
(from a combination of ALGOrithmic and Language); a programming language used to express computer programs as algorithms
An eclipsing binary star in the constellation of Perseus; Beta (u03B2) Persei. It represents the eye of Medusa, whose head is being held by Perseus.
A high-level programming language mostly used for solving mathematical and scientific problems.
Origin: From غول.
a fixed star, in Medusa's head, in the constellation Perseus, remarkable for its periodic variation in brightness
Algol, known colloquially as the Demon Star, is a bright star in the constellation Perseus. It is one of the best known eclipsing binaries, the first such star to be discovered, and also one of the first variable stars to be discovered. Algol is actually a three-star system in which the large and bright primary Beta Persei A is regularly eclipsed by the dimmer Beta Persei B. Thus, Algol's magnitude is usually near-constant at 2.1, but regularly dips to 3.4 every two days, 20 hours and 49 minutes during the roughly 10-hour long partial eclipses. There is also a secondary eclipse when the brighter star occults the fainter secondary. This secondary eclipse can only be detected photoelectrically. Algol gives its name to its class of eclipsing variable, known as Algol variables.
