Constraints on stellar parameters of the SPB star HD182255 from complex asteroseismology
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 em…
Studying the hybrid pulsator 12 Lacertae: mode identification and complex seismic modelling
Wojciech Szewczuk, Przemysław Walczak, Jadwiga Daszyńska-Daszkiewicz
We present identification of the mode degree, l, for all observed frequencies of 12 Lac and results of seismic modelling which consists in fitting simultaneously the centroid mode…
Constraints on model atmospheres from complex asteroseismology of the βCephei stars
Wojciech Szewczuk, Przemysław Walczak, Jadwiga Daszyńska-Daszkiewicz
Using the method termed complex asteroseismology, we derive constraints on model atmospheres, in particular, on the NLTE effects. We fit simultaneously pulsational frequencies and…
Complex asteroseismology of the Slowly Pulsating B-type star HD74560
Przemysław Walczak, Wojciech Szewczuk, Jadwiga Daszyńska-Daszkiewicz
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…
