Abstract
We present first results of the ongoing search for magnetic fields in eight Ap/CP2 stars and one candidate in the Kepler field using the spectropolarimeter of the 6-meter SAO reflector in Russia. Five stars (KIC 4180396, KIC 5264818, KIC 5473826, KIC 6065699, and KIC 8324268) were found to harbor a strong magnetic field. Very likely, KIC 6864569 is also a magnetic star, but more observations are needed. The status of KIC 8161798 and KIC 10324412 remains as yet unclear; no significant field was detected for the CP2 star candidate KIC 6278403. The resulting sample will facilitate research on the connection between magnetic field topologies and surface chemical structures in mCP stars.
