Comprendre l atmosphere du Soleil et celles des etoiles variables a la fin du 19e siecle or, Understanding the Sun and variable stars atmospheres at the end of the 19th Century

Abstract

Guy Boistel questions the Sun / variable stars analogy at the heart of the work of Dutch astronomer Albert Brester. The problem of interdisciplinarity appears in the objectification of the Sun at the end of the 19th century: it is by mixing astronomy, physics and chemistry that Brester tried to apply knowledge of the solar atmosphere to the understanding of variable stars, a fairly confidential field of study still at that time.
