Scientific paper

Low-resolution spectral measurements have been used to determine the temperature and relative radius variations in three pulsating stars of the Delta Sct class. The variations in the radii of Rho Pup and X Cae (HR 1653) are not quite in agreement with radial velocity measurements found in the literature, a discrepancy which may indicate that these stars pulsate aspherically.
