Method for estimating cycle lengths from multidimensional time series: Test cases and application to a massive "in silico" dataset
Nigul Olspert, Maarit Käpylä, Jaan Pelt
Many real world systems exhibit cyclic behavior that is, for example, due to the nearly harmonic oscillations being perturbed by the strong fluctuations present in the regime of si…

Multiperiodicity, modulations and flip-flops in variable star light curves III. Carrier fit analysis of LQ Hya photometry for 1982-2014
Nigul Olspert, Maarit J. Käpylä, Jaan Pelt +4
We study LQ Hya photometry for 1982-2014 with the carrier fit (CF) -method and compare our results to earlier photometric analysis and recent Doppler imaging maps. We first utilize…
