    • Abstract

       

      In our effort to decipher the words and identify the stars as cited in the text Sarvasiddh$\bar{a}$ntar$\bar{a}$jaby Nity$\bar{\rm a}$nanda 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 Viksepa, 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 Mesa 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. Theconfusion about the Dhruvaka (east–west coordinates) is discussed.

    • Continuous Article Publication

      Posted on January 27, 2016

      Since January 2016, the Journal of Astrophysics and Astronomy has moved to Continuous Article Publishing (CAP) mode. This means that each accepted article is being published immediately online with DOI and article citation ID with starting page number 1. Articles are also visible in Web of Science immediately. All these have helped shorten the publication time and have improved the visibility of the articles.
