CCD photometry of the high-amplitude δ Scuti stars V798 Cygni and V831 Tauri.

Abstract (from CDS):

New CCD measurements of the two high-amplitude δ Scuti stars V798 Cyg and V831 Tau were carried out. The double-mode pulsation of V798 Cyg is demonstrated beyond any doubt. The f1Mf2 ratio of 0.800 is confirmed to be related to the unusual shape of the f1 light curve. The properties of the Fourier parameters were revisited also by considering the new light curve of V831 Tau. In particular, the classical double-mode pulsators cannot fill the gap in the R21 distribution. Two new variable stars were discovered in the field of V798 Cyg.
