The CARMENES survey, designed to detect exoplanets orbiting low-mass stars, has conducted nearly a decade of dedicated observations of M dwarfs using dual spectrographs operating in the visible and near-infrared wavelengths. Over this period, the survey has led to the discovery of numerous exoplanets, including several rare and intriguing cool giant planets orbiting M dwarfs—challenging conventional models of planet formation. Beyond detections, CARMENES has provided valuable insights into the wavelength dependence of radial velocity signals, stellar activity signatures, and elemental abundances in low-mass stars. A significant portion of the program has also been devoted to the characterization of planetary atmospheres. In this presentation, I will summarize key scientific outcomes from the CARMENES program, including new constraints on planet occurrence rates around M dwarfs—the most common stars in our galaxy—and how the presence of cool giant planets correlates with stellar mass.
