Since Beta Persei was more accurately studied, it led to the Algol Paradox. Gravity pulled the swirling gas and dust together and resulted in the Demon Star that we today now see. It is possible that the star’s in the Beta Persei system may have formed at the same time or shortly after one another.īeta Persei most likely formed out of a molecular cloud of dust and gas. The primary star is speculated to have around 570 million years. Formationīeta Persei’s origin is currently unknown because the star isn’t associated with any moving star group. The star was associated with the Saturn and Jupiter planets, the diamond gemstone, and the black hellebore plant. In the case of Algol / Beta Persei, the star was associated with bad luck, death by decapitation, violence. They were also associated with gemstones or plants which would bring the stars influence into magic rituals. These stars were associated with planets, influencing them in an astrological sense. Algol was also one of the 15 Behenian Fixed Stars, used in medieval times in magic rituals. It was named as such due to its location in the constellation of Perseus, marking the head of the celestial medusa. The traditional name of Beta Persei, Algol, is of Arabic origin and translates to “head of the ogre.” It was translated into English as the Demon Star. The age of the primary star has been estimated to be at around 570 million years.The hottest star, Beta Persei Aa1, has average surface temperatures of around 13,000 K.The faintest star, Beta Persei Aa2 is 6.92 times brighter than our sun.The second brightest star, Beta Persei Ab, is 10 times brighter than our sun.The brightest star, Beta Persei Aa1 is 182 times brighter than our sun.
Beta Persei Ab has 1.76 solar masses, and around 1.73 solar radii.Beta Persei Aa2 is smaller, having 0.70 solar masses and around 3.48 solar radii.Beta Persei Aa1 has around 3.17 solar masses and around 2.73 solar radii.Algol is also one of the 15 Behenian Fixed Stars – a group of stars used in medieval astrology in magic rituals.The secondary eclipse when the primary yet brighter star occults the fainter secondary star is very shallow and can only be detected photoelectrically.Algol’s magnitude is usually near-constant at 2.1 but regularly dips to 3.4 every 2.86 days during the 10-hour-long partial eclipses.The primary star Beta Persei Aa1 is more luminous and hotter than Beta Persei Aa2 – they pass in front of each other regularly and result in eclipses.Algol’s name is used to class eclipsing variable stars known as Algol variable since the star system itself is one of the first eclipsing variable systems to be discovered.It is located at around 90 light-years / 28 parsecs away from the Sun. Algol is a three-star system consisting of Beta Persei Aa1, Aa2, and Ab.
