The study, led by the Institute of Astrophysics of Andalusia (IAA-CSIC), has validated the planetary nature of four objects of interest from the TESS mission that orbit around K-type stars, which are smaller, cooler, and longer-lived than our Sun. Two of the four planets detected are located on the edge of the “Neptune desert,” a region where a lack of planets with properties comparable to those of Neptune has been detected.
