Multi-Point Gradient Estimation in Turbulence
Theodore Broeren, Kristopher Klein
When studying turbulence, it is often desirable to be able to estimate the local spatial gradient of a vector quantity using in situ measurements from a small number of irregularly…
Modeling hot, anisotropic ion beams in the solar wind motivated by the Parker Solar Probe observations near perihelia
Leon Ofman, Yogesh, Scott A Boardsen +5
Recent observations of the solar wind ions by the SPAN-I instruments on board the Parker Solar Probe (PSP) spacecraft at solar perihelia (Encounters) 4 and closer find ample eviden…
Identification of Ion-Kinetic Instabilities in Hybrid-PIC Simulations of Solar Wind Plasma with Machine Learning
Viacheslav M Sadykov, Leon Ofman, Scott A Boardsen +5
Analysis of ion-kinetic instabilities in solar wind plasmas is crucial for understanding energetics and dynamics throughout the heliosphere, as evident from spacecraft observations…
The Damping and Instability of Ion-acoustic Waves in the Solar Wind: Solar Orbiter Observations
Hao Ran, Daniel Verscharen, Jesse Coburn +6
Observations of solar wind velocity distribution functions (VDFs) commonly reveal fine-scale structures. These features strongly influence kinetic processes such as wave damping an…
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…
Data-Driven Uncertainty Quantification of the Wave-Telescope Technique: General Equations and Application to HelioSwarm
Theodore Broeren, Kristopher Klein
The upcoming NASA mission HelioSwarm will use nine spacecraft to make the first simultaneous multi-point measurements of space plasmas spanning multiple scales. Using the wave-tele…
