Evidence of global periodicity in PSP data: can they be linked to long-period oscillations in solar active regions?
G. Dumbadze, B. M. Shergelashvili, M. Khodachenko +4
The presence of coherent oscillatory signatures in Parker Solar Probe SWEAP datasets, identified through a series of spectral analyses, is addressed, and their possible connection…
Wave instabilities in anisotropic regularized Kappa plasmas: New plasma dispersion functions and numerical validation
Rudi Gaelzer, Dustin L. Schröder, Marian Lazar +1
Plasmas in space and astrophysical environments are frequently found in (quasi-)stationary states not in thermal equilibrium, indicated by velocity distribution functions (VDFs) fe…
Hybrid simulations of the proton beam instabilities in the young solar wind. The formation of hammerhead-like distributions
R. A. López, Shaaban M. Shaaban, M. Lazar +4
Parker Solar Probe (PSP) observations in the young solar wind reveal new properties of both plasma particle velocity distributions (VDs) and associated electromagnetic (EM) wave fl…
Polytropic stellar wind models with strongly localized heating
L. Westrich, B. Shergelashvili, H. Fichtner +1
Polytropic models of stellar winds remain to be useful tools because they allow for a simple description of the energy balance of the expanding plasma without explicitly specifying…
Modeling complex plasma instabilities in space plasmas - Three-component electron formalism of heat-flux instabilities
Dustin L. Schröder, Marian Lazar, Horst Fichtner +2
Despite the fact that electrons observed in situ in space plasmas have three major components-the quasi-thermal core, suprathermal halo, and strahl-the analysis of instabilities tr…
