Alpha Corvi (α Corvi, abbreviated Alpha Crv, α Crv), also named Alchiba , is an F-type main-sequence star and the fifth-brightest star in the constellation of Corvus. Based on parallax measurements made during the Hipparcos mission, it is approximately 49 light-years from the Sun.
Nomenclature.
"α Corvi" (Latinised to "Alpha Corvi") is the star's Bayer designation.
It bore the traditional names "Al Chiba" (Arabic "ألخبا" "al-xibā" "tent") and "Al Minliar al Ghurab" (Arabic "منقار الغراب" "al-manxar al-ghurab") or "Minkar al Ghurab". The latter appeared in the catalogue of stars in the "Calendarium" of Al Achsasi al Mouakket, which was translated into Latin as "Rostrum Corvi" (beak of the crow). In 2016, the International Astronomical Union organized a Working Group on Star Names (WGSN) to catalogue and standardize proper names for stars. The WGSN approved the name "Alchiba" for this star on 12 September 2016 and it is now so included in the List of IAU-approved Star Names.
In Chinese astronomy, Alchiba is called 右轄, Pinyin: Yòuxiá, meaning "Right Linchpin", because it stands alone in the "Right Linchpin" asterism, Chariot mansion (see: Chinese constellation), 右轄 (Yòuxiá), westernized into "Yew Hea" by R.H. Allen.

Properties.
Alchiba belongs to the spectral class F1V and has apparent magnitude +4.00. This star exhibits periodic changes in its spectrum over a three-day period, which suggests it is either a spectroscopic binary or (more likely) a pulsating Gamma Doradus-type variable.
