What Have We Learnt About B-Type Main Sequence Pulsators from the BRITE Data?
Abstract
We summarize our seismic studies of the β Cep/SPB pulsators based on the BRITE data. The results of the complex seismic analysis of ν Eri, α Lup, θ Oph and κ Sco are presented. We also show results for 12 Lac and γ Peg, whose analysis is based on ground-based observations and MOST data, respectively. One of the most important lessons from the analysis of the BRITE data seems to be that hybrid B-type pulsators are a rule rather than an exception. Moreover, models calculated with standard opacity tables cannot explain observed oscillation spectra. Interestingly, similar modifications of the mean opacity profile are necessary for all studied stars.
