A complex asteroseismic study of the hybrid B-type pulsator $ν$ Eridani

We present results of comprehensive seismic modelling of the B-type main-sequence pulsator $ν$ Eridani, which consists in parallel fitting of the pulsational frequencies and corresponding values of the complex, nonadiabatic parameter $f$, defined by the bolometric flux perturbation. This kind of studies, which we call {\it complex asteroseismology}, provides a unique test of stellar opacities. Our results indicate a preference for the OPAL data.
