TESS serves as a formidable tool for investigating stellar variability. Nonetheless, the adaptation of methodologies employed in other space missions, such as Kepler, to deduce long stellar rotation periods or solar-like stellar pulsations has been a challenge. The advent of multiple sectors of data for most stars every two years with the extended

The PLATO stellar analysis pipeline will provide photometric rotation and activity measurements for as many observed stars as possible. This poster is aimed at presenting the scientific abilities of the rotation and activity analysis module that will be implemented in the PLATO pipeline. The strategy combines Fourier analysis, autocorrelation of

The Kepler mission has delivered unprecedented high-quality photometry. These data have impacted numerous research fields including Galactic studies, asteroseismology, and exoplanets, and continue to be an astrophysical gold mine to this day. Because of this, thorough investigations of the ∼200,000 stars observed by Kepler remain of paramount
