Detecting magnetic fields in Ap/Bp stars observed with the K2 space mission
Résumé
To study the effect large-scale magnetic fields have on the interior of hot stars, we compiled a list of chemically peculiar Ap/Bp stars that were observed with K2 with the future goal of investigating their seismic properties employing space-based photometry. A sub-sample was observed with high-resolution spectropolarimetry to detect the anticipated large-scale magnetic field usually hosted by Ap/Bp stars. We confirm the presence of such a field for 75 % of the stars in the sample. Thus, not all stars in the sample host the expected large-scale magnetic field.
