Energy Supply by Low-frequency Break Sweeping for Heating the Fast Solar Wind from 0.3 to 4.8 au

چکیده
Abstract Solar wind protons undergo significant heating during the expansion of solar and turbulence plays an important role in this process. It is believed that energy injected from energy-containing range into inertial then transferred to dissipate heat eventually. However, injection process heliosphere remains unclear. Here we analyze We utilize Helios 2 Ulysses measurements fast at different radial distances 0.29 4.8 au. obtain perpendicular rate based on gradient magnetic moment. estimate for first time supply due sweeping low-frequency break identification corresponding power spectra density profile. find comparable protons, which support idea becomes part as ages. These results help us understand protons.

We test a theory presented previously to account for the turbulent transport of magnetic uctuation energy in the solar wind and the related dissipation and heating of the ambient ion population. This theory accounts for the injection of magnetic energy through the damping of large-scale ow gradients such as wind shear and compression, and incorporates the injection of magnetic energy due to wav...
