Modelling the Heliosphere

Space Science Reviews, 1996
An overview of our present efforts at the Bartol Research Institute in modelling the large-scale interaction of the solar wind with the local interstellar medium is presented. Particular stress is placed on the self-consistent inclusion of neutral hydrogen in the models and both 2D and 3D structure is discussed. Observational implications are noted.

Heliospheric coordinate systems

Planetary and Space Science, 2002
This article gives an overview and reference to the most common coordinate systems currently used in space science. While coordinate systems used in near-Earth space physics have been described in previous work we extend that description to systems used for physical observations of the Sun and the planets and to systems based on spacecraft location ...

Heliospheric Radio Emissions

Space Science Reviews, 1995
A review is given of heliospheric radio emissions. Only radio emissions generated well away from the Sun (beyond a few solar radii) and well away from the magnetized planets are considered. These consist of (1) type III radio bursts, (2) type II radio bursts, and (3) heliospheric 2-3 kHz radio emissions.

The Inner Heliosphere — Outer Heliosphere Comparison for Cosmic Ray Modulation

Space Science Reviews, 1998
This paper summarizes cosmic ray data on both galactic and anomalous particles in the inner and outer heliosphere near the sunspot minimum in 1995 and 1996 at the end of solar cycle 22. These data come from the IMP spacecraft in the inner heliosphere and the Voyager and Pioneer spacecraft in the outer heliosphere.

The Solar Wind — Inner Heliosphere

Space Science Reviews, 1998
The solar wind in the inner heliosphere, inside ~ 5 AU, has been almost fully characterized by the addition of the high heliographic latitude Ulysses mission to the many low latitude inner heliosphere missions that preceded it. The two major omissions are the high latitude solar wind at solar maximum, which will be measured during the second Ulysses ...

The heliosphere after Ulysses

Astrophysics and Space Science, 2001
Launched in October 1990, the ESA-NASA Ulysses mission has conducted the very first survey of the heliosphere within 5 AU of the Sun over the full range of heliolatitudes. With polar passes taking place in 1994 and 1995, the timing of the mission has enabled Ulysses to characterise the global structure of the heliosphere at solar minimum, when the ...

Fast Dust in the Heliosphere

Space Science Reviews, 2001
The dynamics of dust particles in the solar system is dominated by solar gravity, by solar radiation pressure, or by electromagnetic interaction of charged dust grains with the interplanetary magnetic field. For micron-sized or bigger dust particles solar gravity leads to speeds of about 30 to 40 km s−1 at the Earth’s distance.

The dusty heliosphere

2001
Dust in space has been recognized for centuries. Three dusty phenomena in space can be observed by the naked eye: comets, meteors and zodiacal light. In the past the sporadic appearance of bright comets received much attention, and not only from astronomers, because it was linked to exceptional events in human history such as victory or defeat in war ...
