Semi-Supervised Standardized Detection of Periodic Signals with Application to Exoplanet Detection

ICASSP 2022accepted

We propose a numerical methodology for detecting periodicities in unknown colored noise and for evaluating the ‘significance levels’ (p-values) of the test statistics. The procedure assumes and leverages the existence of a set of time series obtained under the null hypothesis (a null training sample…

Using hydrodynamical simulations of stellar atmospheres for periodogram standardization: Application to exoplanet detection

ICASSP 2016accepted

Our aim is to devise a detection method for exoplanet signatures (multiple sinusoids) that is both powerful and robust to partially unknown statistics under the null hypothesis. In the considered application, the noise is mostly created by the stellar atmosphere, with statistics depending on the com…
