The role of collisions with interplanetary particles in the physical evolution of comets
The Moon and the Planets, 1981Effects 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.

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
2004Solar 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.

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, 2000The 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 ...

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 ...

Physical properties of interplanetary dust: laboratory and numerical simulations
2010Laboratory light scattering measurements with the PROGRA2 experiment, in A300-CNES and ESA dedicated microgravity flights or in ground based configurations, offer an alternative to models for exploring the scattering properties of particles with structures too complex to be easily handled by computer simulations [1,2].

Interplanetary Dust - Its Physical Nature and Entry into the Atmosphere of Terrestrial Planets
1981Studies of extraterrestrial particles collected in the stratosphere and from the sea floor indicate that the majority of interplanetary dust is a black, fine grained material similar to carbonaceous chondrites but different from known meteorites in mineralogy and structure.

The suggestion that significant quantities of interplanetary dust are produced by both main-belt asteroids and comets is based on the Infrared Astronomical Satellite (IRAS) detection of dust trails or bands associated with these objects. Gravitational focusing strongly biases all near-Earth collections of interplanetary dust in favor of particles with ...
