TL;DR: In this paper, the properties of the density-parallel magnetic field correlation for these kinetic wave modes are presented and compared to the observational determination of this correlation based on 10 years of Wind spacecraft data.

TL;DR: In this paper, a theoretical foundation for the study of the kinetic cascade is constructed, and the key role played by the entropy cascade, a dual cascade of energy to small scales in both physical and velocity space, is discussed.

TL;DR: In this article, a wavelet-based statistical study of coherent electromagnetic waves in the first perihelion encounter of NASA's Parker Solar Probe (PSP) demonstrates the presence of transverse electromagnetic waves at ion resonant scales which are observed in 30-50\% of radial field intervals.

TL;DR: In this paper, a comparison of three intervals of Ulysses data with synthetic time series generated from a physically motivated turbulence model was made, and it is hypothesized that the observed signatures result from a perpendicular cascade of Alfv?nic fluctuations and a local, non-turbulent population of ion cyclotron or whistler waves generated by temperature anisotropy instabilities.

TL;DR: In this article, a unified framework for the four proton temperature anisotropy instabilities is presented, identifying the associated stable eigenmodes, highlighting the unstable region of wavevector space and presenting the properties of growing eigenfunctions.
