Accretion Disks around Black Holes: Twenty Five Years Later,te in the form of accretion disks were put forward (Burbidge . Prendergast, 1968; Lynden-Bell, 1969). More quantitative studies were made by Shakura (1972). However, the beginning of modern accretion disk physics is traditionally attributed to the two classical articles, one by Shakura & Sunyaev (19作者: irritation 時(shí)間: 2025-3-22 02:33 作者: 同步左右 時(shí)間: 2025-3-22 06:51
