On the Estimation of Solar Energetic Particle Injection Timing from Onset Times near Earth
Alejandro Saiz, Paul Evenson, David Ruffolo +1
We examine the accuracy of a common technique for estimating the start time of solar energetic particle injection based on a linear fit to the observed onset time versus 1/(particl…
Transport and Acceleration of Energetic Charged Particles near an Oblique Shock
D. Ruffolo
We have developed a numerical simulation code that treats the transport and acceleration of charged particles crossing an idealized oblique, non-relativistic shock within the frame…
Deconvolution of Interplanetary Transport of Solar Energetic Particles
D. Ruffolo, T. Khumlumlert, W. Youngdee
We address the problem of deconvolving the effects of interplanetary transport on observed intensity and anisotropy profiles of solar energetic particles with the goal of determini…
Charge States of Solar Cosmic Rays and Constraints on Acceleration Times and Coronal Transport
D. Ruffolo
We examine effects on the charge states of energetic ions associated with gradual solar flares due to shock heating and stripping at high ion velocities. Recent measurements of the…
Formation, Propagation, and Decay of Coherent Pulses of Solar Cosmic Rays
D. Ruffolo, T. Khumlumlert
We have performed numerical simulations of the interplanetary transport of solar cosmic rays. The particles form a coherent pulse within AU after their injection. The gr…
Effect of Adiabatic Deceleration on the Focused Transport of Solar Cosmic Rays
D. Ruffolo
In the framework of focused transport theory, adiabatic deceleration arises from adiabatic focusing in the solar wind frame and from differential solar wind convection. An explicit…
