Turbulence Near the Venusian Bow Shock: Venus Express Observations

Abstract: In terms of composition and size, Venus is an Earth‐like planet without a global intrinsic magnetic field. The Venusian bow shock and magnetosheath, reaching only 10% of the size of the Earth, are formed from the interaction of the solar wind with the Venusian ionosphere. Energy injection from the solar wind to the Venusian space environment can be studied at the bow shock. In this respect, we hypothesize that the spectral scaling features of magnetic fluctuations near the bow shock represent important informa… Show more

“…In the kinetic frequency range, the turbulence has a larger value of α ~ 2.8, in which regime the magnetic energy dissipates into plasma or accumulates by exciting some dispersive waves, like the whistler. The spectral scaling indices have been extensively used to analyze the magnetic field fluctuations and turbulence in the solar wind (e.g., Alexandrova et al 2008Alexandrova et al , 2009Kiyani et al 2009;Bruno and Carbone 2013), in the planetary space environments near Earth (e.g., Vörös et al 2004Vörös et al , 2007Vörös 2011), Mars (e.g., Ruhunusiri et al 2017), and Venus (e.g., Vörös et al 2008a, b;Dwivedi et al 2015;Xiao et al , 2020a.…”

“…It suggests that the shock geometry has an effect on the spectral scalings of downstream magnetic fluctuations, and the bow shock plays a role on the turbulence distribution in the near-Venusian space. Xiao et al (2020a) presented a description of the spectral scalings of magnetic fluctuations at the Venusian bow shock crossings. In terms of the spectral scalings, the dayside-nightside shock crossings exhibit a clear asymmetry.…”
