Her research is on the magnetospheres of Saturn and Jupiter. The study of planets also includes magnetospheres and ionospheres. Many astronomical objects generate and maintain magnetospheres. One can show that this mechanism efficiently works in the magnetospheres of AGN and pulsars. Radio emissions from magnetospheres could be detected with future radio telescopes. Similar considerations were later used to understand the magnetospheres of rotating black holes. Two terrestrial planets (Earth and Mercury) display magnetospheres, and thus have molten metal layers. Hill, T. W. and A. J. Dessler, Plasma motions in planetary magnetospheres. A magnetic sail could also thrust directly against planetary and solar magnetospheres. Mercury and Uranus have offset magnetospheres, which have no satisfactory explanation yet. Her primary research interests include the magnetospheres of Earth, Jupiter, and Saturn. Similarly, all four gas giants have magnetospheres, which indicate layers of conductive fluids. The paper, entitled "Axisymmetric, Nonstationary Black Hole Magnetospheres&colon; Revisited" appeared in the "Astrophysical Journal" (ApJ). His research subject areas are magnetospheric physics, planetary magnetospheres, primarily of Jupiter and planetary science. However, in planetary magnetospheres co-rotational forces are dominant and change the picture slightly.
