Query: Magnetic fields of Herbig Ae/Be stars   We report on the status of our spectropolarimetric studies of Herbig Ae/Be
stars carried out during the last years. The magnetic field geometries of these
stars, investigated with spectropolarimetric time series, can likely be
described by centred dipoles with polar magnetic field strengths of several
hundred Gauss. A number of Herbig Ae/Be stars with detected magnetic fields
have recently been observed with X-shooter in the visible and the near-IR, as
well as with the high-resolution near-IR spectrograph CRIRES. These
observations are of great importance to understand the relation between the
magnetic field topology and the physics of the accretion flow and the accretion
disk gas emission.
