摘要: Abstract The electron distribution functions measured in the neighborhood of Mars by means Hyperbolic Retarding Potential Analyzer (HARP) carried aboard Phobos 2 spacecraft are presented. measurements were out over an energy/charge ( E / q ) from ∼0.3 eV to ∼800 eight independent angular sectors ∼ 20° × 10° covering FOV 180° X - Z plane antisolar directions. total intensity and energy function electrons downstream bow shock clearly differ those undisturbed solar wind. fluxes significantly increased magnetosheath was found be characterized double-peaked structure. high often exceed flux values for low peak.
