FRA – A new Fast, Robust and Automated pipeline for the detection of solar-like oscillations among red giants

Being able to assess the presence of solar-like oscillations in stellar power spectra is a pre-requisite to any seismic analysis. Given the increasing harvest of ligthcurves obtained by the space missions Kepler, TESS, and in the coming years, PLATO, it is crucial to have a fast, robust and automated tool at hand. We developed a new pipeline allowing the Fast, Robust and Automated (FRA) detection of solar-like oscillations. It is based on the detection and measurement of the frequency of maximum oscillation power, νmax, and runs in a few seconds of CPU time. Our pipeline allows to measure νmax independently from the large separation, ∆ν, while using statistical criteria to validate or not the obtained measurement, and thus confirm or not the presence of oscillations. I present here the results we obtain when applying the FRA pipeline to ∼ 1700 Kepler and ∼ 2300 TESS red giants, as well as ∼ 250 artificial power spectra representative of TESS red giants. The analysis of artificial power spectra provides limits in magnitude and in the number of observed sectors required to obtain consistent νmax measurements, while maximizing the detectability of oscillations and minimizing the false positive detections. Since νmax is among the crucial seismic parameters to derive precise and accurate stellar masses and radii, the FRA pipeline represents a huge potential for Galactic archeology and exoplanet characterization.
