The Effect of Different Opacity Data and Chemical Element Mixture on the Petersen Diagram
The Effect of Different Opacity Data and Chemical Element Mixture on the Petersen Diagram
The Petersen diagram is a frequently used tool to constrain model parameters such as metallicity of radial doubleāmode pulsators. In this diagram the period ratio of the radial first overtone to the fundamental mode, Ī 1/Ī 0, is plotted against the period of the fundamental mode. The period ratio is sensitive to ā¦
