Indian siddhāntic texts are well known for their indigenous approach to solutions of problems in astronomy which also speaks of their expertise in mathematics. The text Sūryasiddhānta is considered as an authority and we come across a number of texts as commentaries on this text. They range from 8th Century CE to 19th century CE. The study of the stars that have been listed in the text appears relatively easy for the 27 stars of the zodiac. However, there are other stars for which optical identifications are not easy. Here we present possible identifications for two stars called Āpa and Apāṃvatsa, in the constellation of Virgo. We use the NASA Skyview Survey and other catalogues to see if these two correspond to variable stars.

Āpa 和 Apāṃvatsa – 在 Sūryasiddhānta 编录的神秘恒星

印度 siddhāntic 文本以其解决天文学问题的本土方法而闻名，这也说明了他们在数学方面的专业知识。Sūryasiddhānta 文本被认为是权威，我们遇到了许多文本作为对该文本的注释。它们的范围从公元 8 世纪到公元 19 世纪。对文中列出的星星的研究，对于十二生肖中的 27 颗星星来说似乎相对容易。然而，还有其他恒星的光学识别并不容易。在这里，我们介绍了处女座中两颗名为 Āpa 和 Apāṃvatsa 的恒星的可能识别。我们使用 NASA Skyview Survey 和其他目录来查看这两个是否对应于变星。
