The names of the stars in old Indian texts are listed in the manuals for the use of astrolabes-for example in the Yantrarāja, Sarvasiddhāntarāja and Yantra Kiraṇāvalī-with coordinates and magnitudes. They were forgotten and the names of the stars too were forgotten, leading to confusion in the identification of stars in recent years. Betelgeuse is omitted in the list of 27 bright stars in the old texts. Recent studies have associated it with Ārdrā, while the coordinates from the old manuals clearly point to γ Gem (Alhena).
