Strong Prevalence of Hammerhead Velocity Distributions Close to the Heliospheric Current Sheet

Srijan Bharati Das, Jaye L. Verniero, Samuel T. Badman +13

The solar wind undergoes non-adiabatic heating as it travels away from the Sun. The velocity phase space distribution of non-equilibrium ions in the solar wind indicate a source of…

Tracing a Multi-Temperature Quiescent Prominence's Thermodynamic Evolution from Sun to Earth

Callie A. García, Yeimy J. Rivera, Samuel T. Badman +5

Solar prominences are cool, dense stable structures routinely observed in the corona. Prominences are often ejected from the Sun via coronal mass ejections (CMEs). However, they ar…

Observational Constraints on the Radial Evolution of O Temperature and Differential Flow in the Inner Heliosphere

Yeimy J. Rivera, Kristopher G. Klein, Joseph H. Wang +15

Over decades of solar wind observations, heavy ions have been observed to have a higher temperature and flow faster than protons in the solar corona and heliosphere. Remote observa…

Helium Abundance Periods Observed by the Solar Probe Cup on Parker Solar Probe: Encounters 1-14

Madisen Johnson, Yeimy J. Rivera, Tatiana Niembro +7

Parker Solar Probe is a mission designed to explore properties of the solar wind closer than ever before. Detailed particle observations from the Solar Probe Cup (SPC) have primari…

In situ observations of large amplitude Alfvén waves heating and accelerating the solar wind

Yeimy J. Rivera, Samuel T. Badman, Michael L. Stevens +16

After leaving the Sun's corona, the solar wind continues to accelerate and cools, but more slowly than expected for a freely expanding adiabatic gas. We use in situ measurements fr…

Observed Fluctuation Enhancement and Departure from WKB Theory in Sub-Alfvénic Solar Wind

David Ruffolo, Panisara Thepthong, Peera Pongkitiwanichakul +12

Using Parker Solar Probe data from orbits 8 through 17, we examine fluctuation amplitudes throughout the critical region where the solar wind flow speed approaches and then exceeds…

Observations of Kappa Distributions in Solar Energetic Protons and Derived Thermodynamic Properties

M. E. Cuesta, A. T. Cummings, G. Livadiotis +13

In this paper we model the high-energy tail of observed solar energetic proton energy distributions with a kappa distribution function. We employ a technique for deriving the therm…

Calibrating the WSA model in EUHFORIA based on PSP observations

Evangelia Samara, Charles N. Arge, Rui F. Pinto +5

We employ Parker Solar Probe (PSP) observations during the latest solar minimum period (years 2018 -2021) to calibrate the version of the Wang-Sheeley-Arge (WSA) coronal model used…

Correlation of Coronal Mass Ejection Shock Temperature with Solar Energetic Particle Intensity

Manuel Enrique Cuesta, D. J. McComas, L. Y. Khoo +13

Solar energetic particle (SEP) events have been observed by the Parker Solar Probe (PSP) spacecraft since its launch in 2018. These events include sources from solar flares and cor…

On the Mesoscale Structure of CMEs at Mercury's Orbit: BepiColombo and Parker Solar Probe Observations

Erika Palmerio, Fernando Carcaboso, Leng Ying Khoo +27

On 2022 February 15, an impressive filament eruption was observed off the solar eastern limb from three remote-sensing viewpoints, namely Earth, STEREO-A, and Solar Orbiter. In add…

Multi-point Assessment of the Kinematics of Shocks (MAKOS): A Heliophysics Mission Concept Study

Katherine A. Goodrich, Lynn B. Wilson, Steven Schwartz +6

Collisionless shocks are fundamental processes that are ubiquitous in space plasma physics throughout the Heliosphere and most astrophysical environments. Earth's bow shock and int…

Three-dimensional energy transfer in space plasma turbulence from multipoint measurement

Francesco Pecora, Sergio Servidio, Yan Yang +6

A novel multispacecraft technique applied to Magnetospheric Multiscale (MMS) mission data collected in the Earth's magnetosheath enables evaluation of the energy cascade rate solvi…

CMEs and SEPs During November-December 2020: A Challenge for Real-Time Space Weather Forecasting

Erika Palmerio, Christina O. Lee, M. Leila Mays +20

Predictions of coronal mass ejections (CMEs) and solar energetic particles (SEPs) are a central issue in space weather forecasting. In recent years, interest in space weather predi…
