Abstrakt

Multiple oscillation frequencies separated by close to or less than the

formal frequency resolution of a data set are a serious problem in the

frequency analysis of time series data. We present a new and fully

automated Bayesian approach that searches for close frequencies in time

series data and assesses their significance by comparison to no signal

and a mono-periodic signal. We extensively test the approach with

synthetic data sets and apply it to the 156 days-long high-precision

BRITE photometry of the SPB star HD 201433, for which we find a sequence

of nine statistically significant rotationally split dipole modes.
