Anmerkungen zu parabelfoermigen B-R-Diagrammen.

STEINBACH H.-M.

Abstract (from CDS):

The period of UU Boo increase all the time in a constant rate. Also informations about O-C - diagrams are given. Auf der BAV-Tagung in Heidelberg machte mich Wolfgang Quester auf eine Ungenauigkeit in meinem Artikel im RB 3/2006 zu dem B-R-Ver- halten von UU Boo aufmerksam. Ich schrieb dort, da die B-R-Werte seit Beginn der Beobachtungen im Jahre 1907 bis heute eine sehr aus- geprgte parabolische Form aufweisen, deren Minimum gegen Ende der 60er/Anfang der 70er Jahre des letzten Jahrhunderts lag. Seit dieser Zeit nimmt die Periode des Sterns immer strker wachsend zu". Das ist nicht ganz korrekt, da die Periode des Sternes ber den gesamten Zeitraum hinweg zunahm - und auch nicht strker wachsend, sondern eher mit einer konstanten Rate. Dieser Hinweis veranla?te mich, das Thema "B-R-Diagramme" etwas eingehender zu beleuchten.
