This summer, 310 years will have elapsed since the first ec lipsing binary - Algol - was discovered in Bologna by Geminiano Montanari (1633-1687) to be a variable star; and 198 years have gone by since John Goodricke of York (1764-1786) established the fact that Algol‘s light changes were periodic. Moreover, it is al most exactly (to a month) now 100 years since Edward Charles Pickering (1846-1919) of Harvard Observatory in the United States took the first steps towards the development of systematic methods of analysis of the light changes of Algol and related systems - a topic which will constitute the major part of the programme of our present conference. The three dates recalled above illustrate that the discoverers of such celestial objects and observers of their light changes have been systematically ahead of the theoreticians endea vouring to und | | 出版日期 | Conference proceedings 1981 | | 关键词 | nebula; observatory; photometry; planet; star | | 版次 | 1 | | doi | https://doi.org/10.1007/978-94-009-8486-8 | | isbn_softcover | 978-94-009-8488-2 | | isbn_ebook | 978-94-009-8486-8Series ISSN 1389-2185 | | issn_series | 1389-2185 | | copyright | D.
