Complex asteroseismology of the Slowly Pulsating B-type star HD74560
Abstract
We present the results of complex seismic modelling of the Slowly Pulsating B-type star HD74560. The star pulsates in five frequencies detected in photometric observations. For all these frequencies, we identify the mode degree, . For two of them, found also in spectroscopic data, we are able to derived the empirical values of the complex nonadiabatic parameter f. We test effects of chemical composition and opacity data. Our results show that the properties of seismic models of SPB stars differ significantly from those of the more massive β Cephei stars.
