PARTICLES AND FIELDS IN THE INTERPLANETARY MEDIUM [PDF]

open access: yesProceedings of the National Academy of Sciences, 1967
Man's knowledge of the properties of interplanetary space has advanced radically since 1962, the major part of this advance occurring since the commencement of the International Years of the Quiet Sun. The IQSY has, in fact, been quite unique in that it has seen the augmentation of the extensive synoptic studies of both geophysical and solar phenomena ...

Magnetic field and plasma parameters for magnetic clouds in the interplanetary medium [PDF]

open access: yesGeofísica Internacional, 2000
For a set of 16 magnetic cloud events measured at 1 AU we investigated the magnetic field and plasma parameters in order to characterize the pressure differences between the structure and the environment. The asymmetry profile of the magnetic cloud field

What causes the variations of the peak intensity of CIR accelerated energetic ion fluxes? [PDF]

open access: yesAnnales Geophysicae, 1998
The variation of the peak intensity of energetic ions accelerated at CIR related shocks in the interplanetary medium as observed by instruments on board of ULYSSES during its pass towards the south polar region and from the north polar region back to ...

Enhancing Triangulation of Interplanetary Type III Bursts through Wavevector Correction

open access: yesThe Astrophysical Journal
Interplanetary Type III bursts, generated by relativistic electron beams at solar flare reconnection sites, are explored through an investigation of 152 instances observed by the Solar Terrestrial Relations Observatory mission.

Model Calculations for Cosmogenic Nuclides in Meteorites and the Lunar Surface. 1. Long‐lived Radionuclides

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Production rates for the cosmogenic radionuclides 10Be, 14C, 26Al, 36Cl, 41Ca, 53Mn, and 60Fe in a large variety of meteorites, that is, ordinary chondrites (H, L, LL), carbonaceous chondrites, HED meteorites, ureilites, Martian meteorites, and iron meteorites and in the uppermost ~2 m of the lunar surface are modeled.

Terrestrial ages of meteorites from the Atacama Desert (Chile) and insights into the past meteorite flux to Earth

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract The Atacama Desert in Chile is characterized by its high meteorite density and old meteorite terrestrial ages. In this work, we present new terrestrial ages derived from measurements of the concentration of cosmogenic 36Cl in the metal fraction of 51 ordinary chondrites collected over a 6.8 km2 area located in the Catalina Dense Collection ...

STUDYING AURORAL ACTIVITY USING THE SME INDEX AT THE MAGNETIC STORM MAIN PHASE DURING CIR AND ICME EVENTS

open access: yesSolar-Terrestrial Physics, 2021
In this paper, we examine the relationship of the SME index with magnetic storm characteristics and interplanetary medium parameters during the main phase of magnetic storms caused by CIR and ICME events.

Charged Particle Transport in the Interplanetary Medium [PDF]

open access: yes, 2017
The scenario and fundamentals of the physics of charged particle interplanetary transport are briefly introduced. Relevant characteristics of solar energetic particle (SEP) events and of the interplanetary magnetic field are described. Next, the motion of a charged particle and the main assumptions leading to the description of the focused and ...
