A Living Catalog of Parker Solar Probe IS\ensuremath\odotIS Energetic Particle Enhancements
Energetic charged particles are pervasive throughout the heliosphere with contributions from solar energetic particle events, stream and corotating interaction regions, galactic cosmic rays, anomalous cosmic rays, and suprathermal ions. The Integrated Science Investigation of the Sun (IS\ensuremath\odotIS) on board the Parker Solar Probe is a suite of energetic particle detectors covering the energy range \raisebox-0.5ex\textasciitilde20 keV-200 MeV nuc$^-1$. IS\ensuremath\odotIS measures energetic particles closer to the Su ...

Simulation of the Solar Energetic Particle Event on 2020 May 29 Observed by Parker Solar Probe
This paper presents a stochastic three-dimensional focused transport simulation of solar energetic particles (SEPs) produced by a data-driven coronal mass ejection (CME) shock propagating through a data-driven model of coronal and heliospheric magnetic fields. The injection of SEPs at the CME shock is treated using diffusive shock acceleration of post-shock suprathermal solar wind ions. A time-backward stochastic simulation is employed to solve the transport equation to obtain the SEP time-intensity profile at any location, ...

The Effect of the Fluctuating Interplanetary Magnetic Field on the Cosmic Ray Intensity Profile of the Ground-level Enhancement (GLE) Events
We numerically integrate the equations of motion of a large number of GeV protons, released impulsively near the Sun, in order to study their time-intensity behavior at the location of an observer at 1 au. This is relevant to the interpretation of Ground Level Enhancements (GLEs) detected by neutron monitors on Earth. Generally, the observed time-intensity profiles reveal a single sharp rise, followed by slow decay. However, in the 1989 October 22 GLE event, there was an initial sharp spike followed by a secondary smaller sp ...

Influence of Large-scale Interplanetary Structures on the Propagation of Solar Energetic Particles: The Multispacecraft Event on 2021 October 9
An intense solar energetic particle (SEP) event was observed on 2021 October 9 by multiple spacecraft distributed near the ecliptic plane at heliocentric radial distances R \ensuremath\lesssim 1 au and within a narrow range of heliolongitudes. A stream interaction region (SIR), sequentially observed by Parker Solar Probe (PSP) at R = 0.76 au and 48\textdegree east from Earth (\ensuremath\phi = E48\textdegree), STEREO-A (at R = 0.96 au, \ensuremath\phi = E39\textdegree), Solar Orbiter (SolO; at R = 0.68 au, \ensuremath\phi = ...

Double-power-law Feature of Energetic Particles Accelerated at Coronal Shocks
Recent observations have shown that in many large solar energetic particle (SEP) events the event-integrated differential spectra resemble double power laws. We perform numerical modeling of particle acceleration at coronal shocks propagating through a streamer-like magnetic field by solving the Parker transport equation, including protons and heavier ions. We find that for all ion species the energy spectra integrated over the simulation domain can be described by a double power law, and the break energy depends on the ion ...

Solar Energetic Particle Acceleration at a Spherical Shock with the Shock Normal Angle \\theta \\_\\B\\_\n\\ Evolving in Space and Time
We present a 2D kinematic model to study the acceleration of solar energetic particles (SEPs) at a shock driven by a coronal mass ejection. The shock is assumed to be spherical about an origin that is offset from the center of the Sun. This leads to a spatial and temporal evolution of the angle between the magnetic field and the shock-normal direction (\ensuremath\theta $_ Bn $) as it propagates through the Parker spiral magnetic field from the lower corona to 1 au. We find that the high-energy SEP intensity varies significa ...

Energetic Electron Observations by Parker Solar Probe/IS\ensuremath\odotIS during the First Widespread SEP Event of Solar Cycle 25 on 2020 November 29
At the end of 2020 November, two coronal mass ejections (CMEs) erupted from the Sun and propagated through the interplanetary medium in the direction of Parker Solar Probe while the spacecraft was located at \raisebox-0.5ex\textasciitilde0.81 au. The passage of these interplanetary CMEs (ICMEs) starting on November 29 (DOY 334) produced the largest enhancement of energetic ions and electrons observed by the Integrated Science Investigation of the Sun (IS\ensuremath\odotIS) energetic particle instrument suite on board Parker ...
