Context. A detailed investigation of the magnetic properties of young Sun-like stars can provide valuable information on our Sun’s magnetic past and its impact on the early Earth. Aims. We determine the properties of the moderately rotating young Sun-like star κ Ceti’s magnetic and activity cycles using 50 years of chromospheric activity data and six epochs of spectropolarimetric observations. Methods. The chromospheric activity was determined by measuring the flux in the Ca ii H and K lines. A… Expand
