		| Abstract: | 
		Groups of DAV star models are evolved by WDEC with cores from WD models evolved by MESA. We calculate the pulsating frequencies and study the dispersion of period spacings. Thin H mass corresponds to dispersive period spacings. Studying the dispersion of period spacing for KUV03442+0719, log(MH/M*) is basically from –8.5 to –5.5. |
