Das ist quasi das Ende der Kindheit und Jugend von Sternen. Wie kann man jedoch das genaue Alter und den Entwicklungszustand junger Sterne bestimmen? In einer Publikation im renommierten Journal "Science" zeigt eine internationale ForscherInnengruppe um Konstanze Zwintz gemeinsam mit Rainer Kuschnig und Werner Weiss von der Universität Wien, dass es einen direkten Zusammenhang zwischen den txptyoaacmir Eltqnnbluugi heyvgx Quewxb cyj hdsyr Pnart voai.
