Abstract

In planets that do not have an intrinsic magnetic field, the interaction with the solar wind with them occurs directly with the high atmosphere/ conductive ionosphere of the planet. The solar wind induces currents in the ionosphere that creates forces that tends to draw the solar wind around the planet; this type of magnetosphere is called as induced magnetosphere. The magnetosheath of the induced magnetosphere of Mars has in an addition of planetary ions, which can drastically alters the dispersion of hydromagnetic waves and can produce new types of MHD discontinuities in the transition region. The aim of that project is to identify the major frequencies of electrons oscillation in the Mars magnetosheath for the MEX interval of data (2004-2016) using the wavelet transform. And also investigate whether those waves can transfer energy from solar wind to the ionosphere and by this enhance atmospheric erosion.
