Interplanetary Coronal Mass Ejections Observed in the Heliosphere: 3. Physical Implications

Space Science Reviews, 2009
We conclude the heliospheric image series with this third and final instalment, where we consider the physical implications of our reconstruction of interplanetary coronal mass ejections from heliospheric imagers. In Paper 1 a review of the theoretical framework for the appearance of ICMEs in the heliosphere was presented and in Paper 2 a model was ...

The role of collisions with interplanetary particles in the physical evolution of comets

The Moon and the Planets, 1981
Effects of collisions with interplanetary particles are investigated. To this purpose, collision probabilities for comets with different orbital elements are computed. It is found that collisions may have a non-negligible effect on the physical evolution of comets.

Physical Properties of the Interplanetary Medium

1985
The solar wind is one of the main factors which, along with electromagnetic radiation from the Sun and planets, determines physical conditions in the circumsolar space. This is a more or less continuous plasma flow which is generated in the upper corona of the Sun and carries magnetic fields of solar origin.

Predicting the physical parameters of interplanetary shock waves using Artificial Neural Networks trained on NASA’s ACE and WIND spacecrafts

2020 4th International Symposium on Multidisciplinary Studies and Innovative Technologies (ISMSIT), 2020
This study aims to develop artificial neural networks to predict the physical parameters of the shock waves in the interplanetary (IP) environment which are closely correlated to the sunspot number as demonstrated in previous studies [1] and [2]. This is done by training the ANNs with the current available data and then use the model to predict for the

Overview of Solar Radio Physics and Interplanetary Disturbances

2004
Solar radio emission has been observed from a few hundred GHz down to a few kHz and has revealed a large variety of phenomena. Thanks to this broad frequency window, solar phenomena can be probed from a fraction of a solar radius out to 1 AU and beyond.

Corotating and Propagating Disturbances in the Solar Wind Based on Monitoring of Interplanetary Scintillations at the LPA Radio Telescope of the Lebedev Physical Institute in 2017

Astronomy Reports, 2020
Monitoring of interplanetary scintillations in 2017 is used as a basis for analyzing the dynamics of scintillation levels in periods preceding the arrival at the Earth of eight large-scale disturbances in the solar wind giving rise to strong geomagnetic storms.

Physical interpretation of interdisciplinary solar/interplanetary observations relevant to the 27–29 June 1980 SMY/STIP event no. 5

Advances in Space Research, 1982
Abstract A sequence of six well defined interplanetary structures (magnetic clouds) was identified in the solar wind and magnetic field measurements of Helios-1 from 29 June-01 July, 1980. (location 0.64–0.67 AU, C. Long. ∼165°, C. Lat. ∼5.8°).

Coronal Mass Ejections in September 2017 from Monitoring of Interplanetary Scintillations with the Large Phased Array of the Lebedev Institute of Physics

Astronomy Reports, 2018
Results of monitoring of interplanetary scintillations with the Large Phased Array of the Pushchino Radio AstronomyObservatory at 111 MHz during a period of flare activity of the Sun in the first ten days of September 2017 are presented. Enhancements of scintillations associated with interplanetary coronal mass ejections propagating after limb flares ...

Physics of interplanetary magnetic flux ropes: Toward prediction of geomagnetic storms

Advances in Space Research, 2000
The purpose of this review is to examine the possibility of predicting large geomagnetic storms from solar observations. We focus on three topics: (1) the relationship between coronal mass ejections and interplanetary magnetic flux ropes (hereinafter called flux ropes for simplicity), (2) the role of flux ropes in geomagnetic storms, and (3) further ...

PHYSICAL PROPERTIES OF METEORITES AND INTERPLANETARY DUST PARTICLES: CLUES TO THE PROPERTIES OF THE METEORS AND THEIR PARENT BODIES

Earth, Moon, and Planets, 2004
Meteorites, generally 1 cm or larger in size that are believed to sample asteroids, and interplanetary dust particles (IDPs), generally 5–50 μm in size that are believed to sample both asteroids and comets, span the size range of the meteors. Thus, the physical properties of the meteorites and the IDPs are likely to constrain the properties of the ...
