Collisionless Shocks as a Diagnostic Tool for Understanding Energetic Particle Transport in Space Plasmas

Frontiers in Astronomy and Space Sciences, 2020
We study the transport of energetic particles accelerated at three different shock events observed in the solar wind by the ACE spacecraft. We consider particle propagation for a quasi-parallel, an oblique, and a quasi-perpendicular shock.

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

Experimental Physiology, Volume 111, Issue 9, Page 4015-4040, 1 September 2026.
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

Galactic Cosmic Rays in the Outer Heliosphere [PDF]

, 2010
We report a next generation model of galactic cosmic ray (GCR) transport in the three dimensional heliosphere. Our model is based on an accurate three-dimensional representation of the heliospheric interface.

Exclusion of Tiny Interstellar Dust Grains From the Heliosphere

, 2010
The distribution of interstellar dust grains (ISDG) observed in the Solar System depends on the nature of the interstellar medium‐solar wind interaction.

Electron Shot Noise on a Current Biased Antenna

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract The Parker Solar Probe (PSP) Fields Experiment (FIELDS) uses Radio Frequency Spectrometer (RFS) data and Quasi‐Thermal Noise Spectroscopy (QTN) to determine the temperature and density of electrons in the heliosphere. The FIELDS antennas typically operate with a negative bias current.

ICMEs in the inner heliosphere: origin, evolution and propagation effects

, 2006
This report assesses the current status of research relating the origin at the Sun, the evolution through the inner heliosphere and the effects on the inner heliosphere of the interplanetary counterparts of coronal mass ejections (ICMEs).

Heliospheric consequences of solar activity in geophysical and interplanetary phenomena

Geofísica Internacional, 2004
We have done an analysis of the total solar magnetic flux, polar coronal hole area and sunspots. We investigate their long term evolution over several solar cycles and their possible relationship with interplanetary shocks, sudden storm commencements at ...

Near‐Earth Cosmic Ray Modulation Index ϕ and Neutron Monitor Cutoff Rigidities at Hourly Cadence: Toward an Improved Monitoring of Solar‐Terrestrial Radiation Environment, Space Weather, and Space Climate

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Cosmic rays (CRs) are energetic particles originating from galactic and extragalactic sources. When arriving into the solar system and the Sun's heliosphere, they are diverted and modulated by the magnetic activity of the Sun. This modulation can be quantified by the modulation parameter ϕ $\phi $ determined with the Force‐field approximation (

Collisional thermalization of minor ions in the solar wind

Frontiers in Astronomy and Space Sciences
IntroductionAs the solar wind transits through the heliosphere, Coulomb collisions among constituent particles drives it toward local thermodynamic equilibrium. Prior studies of ion collisions in the solar wind have focused on the two most abundant solar
