Magnetic Doppler imaging of alpha2 Canum Venaticorum in all four Stokes parameters. Unveiling the hidden complexity of stellar magnetic fields
The authors studied the stellar magnetic field of alpha2 CVn using spectra in all four Stokes parameters. They infer a surprisingly complex field topology, supporting the view that only full Stokes vector observations allow one to detect and reconstruct small-scale stellar surface magnetic field structures.
