1212.4643 (Przemysław Walczak et al.)

Constraints on stellar parameters of the SPB star HD182255 from complex asteroseismology    [PDF]

Przemysław Walczak, Wojciech Szewczuk, Jadwiga Daszyńska-Daszkiewicz
Seismic modeling of the Slowly Pulsating B-type star HD182255 yields strong constraints on the radial orders of the two dominant modes. For these frequencies, we derive also the empirical values of the complex nonadiabatic parameter $f$. These two seismic tools, i.e., pulsational frequencies and the associated values of $f$, allow to test available opacity data, chemical composition and overshooting efficiency.
