Amplitude investigation of δ Scuti variables in open clusters.
LI Z.P. and MICHEL E.
Abstract (from CDS):
We report here the results of a statistical analysis of 28 δ Scuti stars from five open clusters, α Persei, Pleiades, Hyades, Praesepe and Coma. These δ Scuti variables, most of which are on the main sequence, tend to show a positive correlation between oscillation amplitude and absolute luminosity. No correlation is found between amplitude and effective temperature.
