Constraints on stellar parameters of the slowly pulsating B star HD 182255 from complex asteroseismology
Abstract
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.
