in yavan vidvanon ne ‘vrihadyavan jatk’ aur ‘laghu yavan jatk’ granthon ki rachna ki. inke jyotish gyan ke karan inhen rishi tulya samman mila. us samay ke bhartiya jyotishiyon men bhattotpal, kalyan varma, vaidyanath, brahmagupt, manujal, mahaviracharya, chand¬rasen, shripti, shridhar aur bhattavosri ne in yavan vidvanon ke prati kritagyata prakat ki. san 1016 men albruni aur ijva 1031 ke bich mohammad gajnvi ke sath bharat ae aur san 1031 tak yahan rahakar bhartiya jyotish ka gahan adhyayan kiya. albruni ne jyotish ke ganit paksh ke jyotish siddhant aur us samay ke pramukh bhartiya jyotishiyon ka vistar se ullekh kiya. yah uska yogdan tha. madhyakal men bhi anek muslim jyotirvid hue jinhonne arbi, farsi aur sanskrit bhashaon men jyotish granthon ki rachna ki. inmen kuch hastalikhit sahitya to aj bhi hain sangrahalyon men upalabdh hain.
