Abstract
A comprehensive list of 178 known δ Scuti and RR Lyrae-stars is presented. Using this revised list a HR diagram for these ultra short period pulsating stars is plotted and the blue and red edges of the resultant instability strip are determined.
Selection effects are discussed, and the PLC relationship of Breger (1979) is tested using data from this list. Stars lying outside the defined instability region are discussed.
