Descripción
We report here the discovery of very low amplitude oscillations in the
Pleiades star HD 23628. The 14-nights high quality light curve
designates HD 23628 as a new member of the δ Scuti stars class.
Amplitude spectra indicate a multi-periodic pulsation behaviour, and
four pulsation frequencies have been detected so far. The frequency
distribution suggests the presence of nonradial modes. Pulsation
constant values of the four modes are distributed in the range
corresponding to fundamental f to p4 radial modes.
