The mode selection problem in delta Scuti stars

  title={The mode selection problem in delta Scuti stars},
  author={Luis A. Balona},
ABSTRACT Inspection of the periodograms of 9597 TESS δ Scuti stars indicates that there is little, if any, correlation between the frequencies and location of the stars in the H–R diagram. A quantitative measure of similarity is described which can be used to compare two frequency spectra. When applied to non-adiabatic pulsation models, the expected strong correlation is found between the predicted pulsation frequencies for models with similar temperatures and luminosities. The correlation is… Expand
