Quantitative Deutung der Fraunhofer-Linien in den Spektren der Sonne und „normaler“ Sterne

  • Chapter
Physik der Sternatmosphären

  • 74 Accesses

Zusammenfassung

Nachdem wir in Kap. X–XIV den Absorptionskoeffizienten und in Kap. XV bis XVI den Strahlungsaustausch in den Fraunhofer-Linien behandelt haben, wenden wir uns nunmehr der eigentlichen Deutung der gemessenen Linienkonturen und Äquivalentbreiten (Kap. IX) zu. Wir beschränken uns dabei in der Hauptsache auf „normale“ Sternatmosphären, die also durch ein Modell mit planparalleler Schichtung hinreichend genau dargestellt werden können. Unser Ziel wird sein die quantitative Bestimmung der Häufigkeit der chemischen Elemente sowie der effektiven Temperatur T e , der Schwerebeschleunigung g und evtl. weiterer Parameter, die den Stern kennzeichnen, aus den Beobachtungen.
