This is an astrometric binary system.[7] The visible component is an F-type main sequence star with a stellar classification of F6 V.[3] It is around 2.4 billion years old[4] and has a high abundance of elements other than hydrogen and helium when compared to the Sun.[5]
Name
This star, along with δ Ari, ε Ari, ζ Ari, and π Ari, were Al Bīrūnī's Al Buṭain (ألبطين), the dual of Al Baṭn, the Belly.[8] According to the catalogue of stars in the Technical Memorandum 33-507 - A Reduced Star Catalog Containing 537 Named Stars, Al Buṭain were the title for five stars : δ Ari as Botein, π Ari as Al Buṭain I, ρ3 Ari as Al Buṭain II, ε Ari as Al Buṭain III dan ζ Ari as Al Buṭain IV[9]
