On the Principal Asteroseismic Diagnostic Signatures

Many stellar model calibrations against seismic data will utilize justthe so-called large and small frequency separations. In this report Iexplain in physical terms, based on resonance conditions forconstructive interference between simple waves,why those frequency separations depend on the variation of sound speedthrough the star in the manner in which they do. By so doing I hope toincrease appreciation of the nature of the stellar calibrations,and thereby provide a means for assessing the credibility of the results.
