Context.Exoplanet properties crucially depend on the parameters of their host stars: more accurate stellar parameters yield more accurate exoplanet characteristics. When the exoplanet host star shows pulsations, asteroseismology can be used for an improved description of the stellar parameters.Aims.We aim to revisit the pulsational properties ofβPic and identify its pulsation modes from normalized amplitudes in five different passbands. We also investigate the potential presence of a magnetic field.Methods.We conducted a frequency analysis using three seasons of BRITE-Constellation observations in the two BRITE filters, the about 620-day-long bRing light curve, and the nearly 8-year-long SMEI photometric time series. We calculated normalized amplitudes using all passbands and including previously published values obtained from ASTEP observations. We investigated the magnetic properties ofβPic using spectropolarimetric observations conducted with the HARPSpol instrument. Using 2D rotating models, we fit the normalized amplitudes and frequencies through Monte Carlo Markov chains.Results.We identify 15 pulsation frequencies in the range from 34 to 55 d⁻¹, where two, F13 at 53.6917 d⁻¹and F11 at 50.4921 d⁻¹, display clear amplitude variability. We use the normalized amplitudes in up to five passbands to identify the modes as three ℓ = 1, six ℓ = 2, and six ℓ = 3 modes.βPic is shown to be non-magnetic with an upper limit of the possible undetected dipolar field of 300 Gauss.Conclusions.Multiple fits to the frequencies and normalized amplitudes are obtained, including one with a near equator-on inclination forβPic, which corresponds to our expectations based on the orbital inclination ofβPic b and the orientation of the circumstellar disk. This solution leads to a rotation rate of 27% of the Keplerian breakup velocity, a radius of 1.497 ± 0.025R_⊙, and a mass of 1.797 ± 0.035M_⊙. The ∼2% errors in radius and mass do not account for uncertainties in the models and a potentially erroneous mode-identification.
