Foreshock and magnetosheath waves in Uranus and Neptune magnetospheres are studied in this work with wavelet analysis. In order to conduct this study, Voyager-2 magnetometer 3-s averaged data are used. The Morlet wavelet transform is applied to the magnetic field vector data. Waves present in the magnetosheath and foreshock regions are highly non-stationary, showing large amplitude variations. It was found that the dominant periods of these waves are longer than the H+ cyclotron period. Overall, high frequency waves are seen near the bow shock crossing and low frequency oscillations near the magnetopause crossing. It can be concluded that non-stationary foreshock and magnetosheath planetary waves can be well characterized with wavelet analysis. (C) 2009 COSPAR. Published by Elsevier Ltd. All rights reserved.
