A global magnetic potential model for Venus' ionosphere
Venus represents the prototype for a class of objects whose interaction with the solar wind is characterized by the dominance of an ionospheric obstacle to the magnetized plasma. Though the interaction region between the ...
Observations of dayside magnetopause oscillations and concurrent temporal variations in cusp precipitation
On April 13, 1996, while Russia's Interball Tail spacecraft was travelling through the dayside magnetosheath, NASA's Polar spacecraft traversed the northern cusp. Transients observed in the data from the Interball Tail/SCA-1 ...
Infrared spectroscopy of Mars
When measured with sufficient spectral range, resolution, and signal-to-noise ratio, nearly every mineral has a unique infrared spectral signature. However, determining which minerals are present on Mars using infrared ...
Dynamics of relativistic electrons during magnetic storms
Our society increasingly relies on spacecraft operations in the Earth's inner magnetosphere, particularly for communications. Long-duration high-intensity fluxes of relativistic electron are hazardous to spacecraft operational ...
A computational investigation of solar energetic particle trajectories in model magnetospheres
This work studies the dynamic behavior of solar energetic particles (SEPs, defined as protons and electrons with energies of 1 MeV to 1 GeV) by simulating their motion in model electromagnetic fields. Because of the hazards ...
Evidence of electron impact ionization in the magnetic pileup boundary of Mars: Observations and modeling results
We analyze the solar wind interaction with Mars through examination of Mars Global Surveyor Magnetometer/Electron Reflectometer (MGS MAG/ER) data. We focus on data in the postshock, dayside plasma flow, especially the ...
