a) Sketch of the location of Jovian radio sources in Jupiter’s inner magnetospheric field lines (in orange): (1) thermal; (2) auroral; (3) radiation belts. Ω, B, and M are the rotation vector, the magnetic field, and the magnetic moment, respectively. The angle β is the tilt between the rotation axis and the magnetic moment. b) Corresponding typical spectra (in Jansky normalized to 4.04 AU, adapted from Zarka 2004), with indication of LOFAR’s low (LBA = low-band antennas) and high (HBA = high band antennas) spectral bands. DAM and DIM are the official denomination of the decameter and the decimeter emissions.
