Wave Emission and Absorption in a Near-Sun Proton-Cyclotron Wave Storm

Kristopher G Klein, Daniel Verscharen, Mihailo Martinovic +5

Quantification of energy transport and dissipation in weakly collisional heliospheric plasmas that are far from local thermodynamic equilibrium is an outstanding scientific problem…

Solar Wind Heating Near the Sun: A Radial Evolution Approach

Yogesh, Leon Ofman, Kristopher Klein +19

Characterizing the plasma state in the near-Sun environment is essential to constrain the mechanisms that heat and accelerate the solar wind. In this study, we use Parker Solar Pro…

Velocity-Space Signatures of Energy Transfer for Ion-Acoustic Instabilities

Mahmoud Saad Afify, Kristopher G. Klein, Mihailo M. Martinović +1

Context. Observations by Parker Solar Probe (PSP) of electrostatic waves suggest that electrostatic instabilities, including the ion-ion-acoustic instability (IIAI) frequently obse…

Free Energy Sources of Ion-scale Waves Observed by Parker Solar Probe

Niranjana Shankarappa, Kristopher G. Klein, Mihailo M. Martinović +6

Parker Solar Probe (PSP) observes abundant circularly polarized ion-scale waves throughout the inner heliosphere. These waves are a signature of the interplay between plasma microi…

How the Oblique Drift Instability Alters Solar Wind Heating and Constrains the Distribution of Solar Wind Observations

Mihailo M. Martinovic, Kristopher G. Klein, Leon Ofman +6

Ion-driven plasma instability thresholds, derived from linear theory, constrain the distribution of solar observations in parameter space, defining boundaries of stable plasma para…
