Āpa, also named Āpyavasu, is an Indian star name in Early Modern times. The only indication of the position is Apavatsa is 5° to the north of Chitra (Spica) and Apa is further 6° to the north, so Apa is 11° north of Spica. No information on magnitudes is preserved.[1]
Concordance, Etymology, History
Āpyavasu means "offspring of Āpa". It is given in Candraśekhara (19th century) that these two terms identify with the same star, although it appears confusing that Apa is identified with its offspring.
Origin of Constellation
The text Sūryasiddhānta is considered as an authority from the 8th to the 19th century CE, but the author(s) remain unknown. Its date is estimated to the 4th or 5th century. It contains a chapter with lists of coordinates and names of stars, which allows for identifications.
