DOIAbstract
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 yr of chromospheric activity data and six epochs of spectropolarimetric observations. Methods. The chromospheric activity was determined by measuring the flux in the Ca I
