In our effort to decipher the words and identify the stars as cited in the text Sarvasiddhāntarāja by Nityānanda of 15th century, we have found that most of the stars near the ecliptic belt are easily identifiable. The coordinate system used is Dhruvaka and Vikṣepa , which differ from the currently used ecliptic longitude–latitude and Right Ascension–declination coordinates. Most of the stars studied hitherto (Pai & Shylaja 2016, 2019; Shylaja & Pai Curr Sci 2018a, 2018b, 2019) were all in the northern hemisphere. It may be recalled that the name of the zodiacal sign (Pai & Shylaja 2016) for a group includes stars with all declinations – both north and south. For example, the group of Meṣa includes the stars of Andromeda. The only two southern stars that were mentioned in the group of Gemini are Sirius and Canopus. Here, we study the stars grouped under Libra and Scorpio, which includes bright stars in the southern hemisphere. The confusion about the Dhruvaka (east–west coordinates) is discussed.

印度天文目录中发现的南方恒星

在我们努力破译单词并识别 15 世纪 Nityānanda 的 Sarvasiddhāntarāja 文本中引用的星星时，我们发现黄道带附近的大多数星星都很容易识别。使用的坐标系是 Dhruvaka 和 Vikṣepa ，它们不同于目前使用的黄道经纬度和赤经坐标。迄今为止研究的大多数恒星（Pai & Shylaja 2016、2019；Shylaja & Pai Curr Sci 2018a、2018b、2019）都在北半球。可能还记得，一组星座的名称 (Pai & Shylaja 2016) 包括所有赤纬的恒星——包括南北。例如，Meṣa 群包括仙女座的星星。双子座中提到的仅有的两颗南方恒星是天狼星和老人星。这里，我们研究天秤座和天蝎座下的恒星，其中包括南半球的明亮恒星。讨论了关于 Dhruvaka（东西坐标）的混淆。
