  • A unique application of the observation of stars in Indian astronomical texts 
    Shylaja, B. S; Shubha, B. S (National Astronomical Research Institute of Thailand, 2024-09)
    It is very well known that the observation of stars constituted an integral part of Indian astronomical texts. The twenty seven stars along the zodiac were used as references for longitudes. Here we discuss an application ...
