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 light curves of solar-like stars provide information on stellar rotation and magnetic activity thanks to active-region crossings. In this work, we investigate the temporal variation of the photometric magnetic activity of the Sun and Kepler solar-like stars. We find that the most active stars are those exhibiting the most significant variations

Solar granulation is the visible signature of convective cells emerging from the upper convective zone towards the solar surface. High-resolution images have revealed the complexity of the granulation, evidencing special phenomena such as exploding granules or granular lanes, which are known to be directly related to the emergence of small-scale
