The heliospheric modulation of cosmic rays: effects of a latitude dependent solar wind termination shock
(Elsevier, 2010)
Observations made with the two Voyager spacecraft confirmed that the solar wind decelerates to form the heliospheric termination shock and that it has begun its merger with the local interstellar medium. The compression ...
Cosmic rays in the dynamic heliosheath
(Elsevier, 2008)
Cosmic ray modulation in the outer heliosphere is discussed from a modeling perspective. Emphasis is on the transport and acceleration of these particles at and beyond the solar wind termination shock in the inner heliosheath ...
Solar cycle variations and cosmic rays
(Elsevier, 2008)
Cosmic rays are excellent indicators of the various solar cycle variations. Galactic and anomalous cosmic rays encounter an outward moving solar wind with cyclic magnetic-field fluctuations and turbulence, which constitute ...
Time-dependent modulation of cosmic rays in the heliosphere
(Springer, 2014)
The time-dependent modulation of galactic cosmic rays in the heliosphere is studied
by computing intensities using a time-dependent modulation model. By introducing recent
theoretical advances in the transport coefficients ...
Challenges to cosmic ray modeling: from beyond the solar wind termination shock
(Elsevier, 2008)
Voyager 1 crossed the solar wind termination shock on December 16, 2004 at a distance of 94 AU from the Sun, to become the first spacecraft to explore the termination shock region and to enter the heliosheath, the final ...
On cosmic ray modulation beyond the heliopause: where is the modulation boundary?
(IOP Publishing, 2011)
Two of the paradigms in modeling the transport of galactic cosmic rays are that the modulation boundary is the heliopause and that the local interstellar spectra are identical to the galactic cosmic ray spectra. Here we ...
Latitudinal gradients of galactic cosmic rays during the 2007 solar minimum
(IOP Publishing, 2008)
Ulysses, launched in 1990 October in the maximum phase of solar cycle 22, completed its third out-of-ecliptic orbit in 2008 February. This provides a unique opportunity to study the propagation of cosmic rays over a wide ...
The effects of magnetic field modifications on the solar modulation of cosmic rays with a SDE-based model
(Elsevier, 2016)
A numerical model for the solar modulation of cosmic rays, based on the solution of a set of stochastic differential equations (SDEs), is used to illustrate the effects of modifying the heliospheric magnetic field, ...
Longitudinal variation of the pickup-proton-injection efficiency and rate at the heliospheric termination shock
(EDP Sciences, 2008)
Context. Pickup ions are considered to be the seed population of the anomalous cosmic rays. The acceleration of the pickup ions at the solar wind termination shock depends on the efficiency with which they are injected ...
Short-term variation in the galactic cosmic ray intensity measured with the PAMELA experiment
(PoS, 2017)
New results on the galactic cosmic ray (GCR) short-term intensity variation associated with Forbush
decrease and co-rotating interaction regions (CIRs) measured by the PAMELA instrument
between November 2006 and March ...
