Multi-spacecraft Investigation of ICME-driven Interplanetary Shock Interaction on the Solar Wind Turbulence in the Inner Heliosphere
Original language description
Recent space missions enable multi-point analysis of solar wind turbulence inthe inner heliosphere. We identify an ICME event in March 2022, and estimate changes ofspectral properties such as spectral index, magnetic helicity, and magnetic compressibilityacross an ICME-driven shock using the spacecraft of Solar Orbiter, ACE, DSCOVR, andWind. Another ICME event identified by Trotta et al. [2023] is adopted for the comparisonof these properties. Despite a small number of events leading to inconclusive results ofevolution with the heliocentric distance, several common trends are observed in both cases:little change of spectral steepness, decreasing jump of magnetic helicity and compressibility, and increasing power enhancement of fluctuations from up- to downstream with theheliocentric distance. However, for a deeper insight on the nature of the radial propagationof these parameters, statistical analyses with a larger number of events are essential.
