Oscillations of BT Cancri in the Praesepe cluster.

FREYHAMMER L.M., LARSEN S.S. and PETERSEN J.O.

Abstract (from CDS):

CCD observations in Johnson B of BT Cancri = HD 73575, the brightest δ Scuti variable in the Praesepe cluster, obtained on three nights in February 1994 are described. Using least squares Fourier decomposition, two modes of oscillation frequencies 9.783 and 7.005c/d and amplitudes of 18.0 and 9.9mmag, respectively, are determined. Comparison with data from the literature indicate that BT Cnc may show secular variations in the oscillation spectrum.
