  The Antartica Search for Transiting Extrasolar Planets (ASTEP), an
automatized 400 mm telescope located at Concordia station in Antarctica,
monitored beta Pictoris continuously to detect any variability linked to the
transit of the Hill sphere of its planet beta Pictoris b. The long observation
sequence, from March to September 2017, combined with the quality and high
level duty cycle of our data, enables us to detect and analyse the delta Scuti
pulsations of the star. Time series photometric data were obtained using
aperture photometry by telescope defocussing. The 66 418 data points were
analysed using the software package Period04. We only selected frequencies with
amplitudes that exceed four times the local noise level in the amplitude
spectrum. We detect 31 delta Scuti pulsation frequencies, 28 of which are new
detections. All the frequencies detected are in the interval 34.76-75.68 d-1 .
We also find that beta Pictoris exhibits at least one pulsation mode that
varies in amplitude over our monitoring duration of seven months.
