概要: application/pdf<br />Departmental Bulletin Paper<br />We examined some apparent close approaches between the Moon and a planet which are recorded in two Vietnamese historical sources, "Dai-Viet Su-Ky Toan-Thu" and "Kham-Djnh Viet-Sir … Thong-Giam Cuong-Muc" by comparing their description with the corrsponding theoreticla prediciton based on a simulation software. There are seven articles(AD1448-1719) on such close approaches, among which one is about and occultation of Venus by the Moon, while thye others six are about the Moon's trespassing on a planet. Our calculation shows that, among these seven articles, three of them are very reasonable(apparent distances of <~1 between the Moon and a planet), one is marginally acceptable(a possible one-day shift of the date) and the other three are hardly acceptable(apparent distances of >~ 5) 続きを見る
