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 New Robotic Telescope (NRT) is an international initiative to build a 4-metre robotic telescope. With a primary mirror consisting of 18 segmented hexagonal mirrors and a control system that will allow fully autonomous operation, NRT will be the world's largest robotic telescope. This, together with a response time of less than 30 seconds, a

The Sun's convective envelope generates, by dynamo effect, a surface magnetic field whose strength evolves on an 11-year cycle, with a change in polarity at the end of each cycle. Similar activity cycles exist in other solar-type stars, influencing the stars' dynamics, including the properties of acoustic oscillations, which are excited by
