Leung, K.-C., 1970: An interpretation of δ Scuti stars. Astron. J., 75, 643-650, doi:10.1086/110999.
Consistent absolute magnitudes are obtained for δ Scuti stars using Strömgren intermediate-band colors and Crawford's photoelectric Hβ indices. A period-color-luminosity relation is found for these variables and the derived contours of constant period in the color-magnitude diagram are almost parallel to the zero-age main sequence. From the locations of 34 known variables and 168 possible nonvariables, two distinct instability regions are found in the H-R diagram; the short-period group lies very close to the zero-age main sequence, while the long-period group lies about 2 mag above the main sequence.
