Scientific paper

A total of 321 observations of the Delta Scuti star BD -6°4932, obtained in 1968 by Hall and Mallama (1970), are analyzed. We find four frequencies which represent the light curves satisfactorily. The three periods: P~ = O~24O, P3 = O~182 and P4 O~114 seem to correspond to the radial modes of pulsation with K = 0, 1, and 3, respectively. The last period P2 = O~22O can be related to a non-radial mode
