Metargon and the Interplanetary Medium [PDF]

open access: yesNature, 1898
THE detection of metargon, and the statement that its spectrum, at all events, closely agrees with the Swan-spectrum, seems to possess a very great interest for the physics of our solar system. It gives a new and expected support to the assumption of an interplanetary atmosphere, which, as I shortly hope to show, will enable us to indicate the solution

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 ...

How Common is Energetic ^3He in the Inner Heliosphere? [PDF]

open access: yes, 2003
Using data from the SIS and ULEIS instruments on the Advanced Composition Explorer (ACE) we have identified periods during which energetic ^3He is present in near-Earth interplanetary space between November 1997 and May 2002.

Observation of Interplanetary Scintillation with Single-Station Mode at Urumqi

open access: yes, 2010
The Sun affects the Earth's physical phenomena in multiple ways, in particular the material in interplanetary space comes from coronal expansion in the form of inhomogeneous plasma flow (solar wind), which is the primary source of the interplanetary ...

Impact risk from the circumsolar dust ring on Venus’s orbit

open access: yesAstronomy & Astrophysics
Context. A circumsolar dust ring on Venus’s orbit was discovered following observations by the Helios spacecraft and then confirmed thanks to observations by STEREO and the Parker Solar Probe.

Investigating Alfvénic Turbulence in Fast and Slow Solar Wind Streams

open access: yesUniverse, 2022
Solar wind turbulence dominated by large-amplitude Alfvénic fluctuations, mainly propagating away from the Sun, is ubiquitous in high-speed solar wind streams. Recent observations performed in the inner heliosphere (from 1 AU down to tens of solar radii)

Interplanetary scintillation observations of the solar wind close to the Sun and out of the ecliptic [PDF]

open access: yes, 1983
A brief review is given of recent developments in the observation of the solar wind by the method of interplanetary scintillation. The emphasis is on observations of the velocity structure, the electron density and the effect of propagating disturbances ...

Interplanetary Type III Radio Emission Locations Deduced from the Underlying Electron Exciter Beam Kinematics

open access: yesThe Astrophysical Journal
Direction-finding techniques from spacecraft have been used to locate and track interplanetary type III radio sources for many decades. These source locations are typically found to be farther from the Sun than expected on the bases of interplanetary ...
