Photometric results from the HIPPARCOS mission are of interest to stellar seismology. HIPPARCOS provides a general description of the HR diagram in terms of stability, microvariability and variability. The satellite has detected systematically variables with amplitudes exceeding a threshold, strongly magnitude dependent but as small as a few mmag for bright stars. When the signal is periodic, periods and amplitudes are determined. Because of the peculiar time sampling of HIPPARCOS only first modes and associated amplitudes are generally obtained. This information is particularly relevant to seismology in the case of pulsating stars as δ Scuti stars, slowly pulsating B stars and β Cephei stars.
