Heating of the interstellar medium by the solar wind

Planetary and Space Science, 1983
The heating of inflowing interstellar gas by the solar wind is calculated. The experimental differential cross sections have been used for calculating electron-H(He) and proton-H(He) elastic scattering rate coefficients. The solar wind is assumed to be a two-component (protons and electrons), steady, spherically symmetric stream moving radially outward,

Anisotropic MHD Turbulence in the Interstellar Medium and Solar Wind

AIP Conference Proceedings, 2003
A theoretical model is given of anisotropic magnetohydrodynamic turbulence in the interstellar medium and the solar wind. The model is motivated by observations that show significant deviations from the Kolmogorov power‐law. Dimensional and heuristic arguments are given and critically assessed. On the basis of the weak turbulence approximation in which

Connection of the solar wind with the interstellar medium through numerical modeling

AIP Conference Proceedings, 2013
In this paper we investigate the interaction between the solar wind (SW) and the local interstellar medium (LISM) using spacecraft data and numerical simulations. In particular, we will focus on neutral atom results from NASA’s Interstellar Boundary EXplorer (IBEX) mission, and compare these with implementations of our neutral atom models that look at ...

Interaction of pulsar winds with interstellar medium

AIP Conference Proceedings, 2005
Time dependent numerical simulations show that the anisotropy of the energy flux and a weak magnetization of the pulsar winds result into formation of the most spectacular features in the central part of the plerions, namely the X‐ray tore and jet‐like outflows. We present the results of such simulations performed by our group.

Shielded by the wind: the influence of the interstellar medium on the environment of Earth

Journal of Atmospheric and Solar-Terrestrial Physics, 2002
We report on the recent studies on the long-term influence of cosmic rays on the Earth's environment. While on short time-scales solar activity is the driver for atmospheric changes suspected to be due to cosmic rays, for long time-scales the heliosphere, i.e.

Interaction of a nonuniform solar wind with the local interstellar medium

Journal of Geophysical Research: Space Physics, 1996
Results from a fully time dependent three‐dimensional gasdynamic model of the interaction of the solar wind with the local interstellar medium are presented. Both subsonic and supersonic interstellar winds are considered, while the mediating effects of interstellar neutrals, magnetic fields, and cosmic rays are ignored.

On the motion of wind-driving stars relative to the ambient interstellar medium

Astrophysics and Space Science, 1995
It is argued that each wind-driving star is subject to the action of thrust forces appearing in relative motion of the star with respect to the ambient interstellar medium. Starting from hydrodynamic modelling of the stellar wind system in an adiabatically adapted motion relative to the local interstellar medium, the equation of star motion is derived ...

Solar wind and interstellar medium coupling

2008
An overview is given of the current state of theory and modelling for the interaction between the solar wind and the interstellar medium (ISM). The final frontiers of the solar wind, as it pushes itself into the ISM, have been an object of speculation and analysis for many years.

Unsteady processes in the solar wind interaction with the local interstellar medium

AIP Conference Proceedings, 2007
In this paper we discuss physical phenomena that could make the solar wind (SW) termination shock (TS) asymmetric enough to explain observations made by the Voyager 2 spacecraft that suggest that the TS is closer to the Sun by about 12 AU in the Voyager 2 than in the Voyager 1 direction. It is shown that the interstellar magnetic field (ISMF) itself is

Stellar Winds and their Interaction with the Interstellar Medium

1983
The most massive stars are losing mass in the form of a more or less steady stellar wind, which blows during most of their lifetime. The energy and momentum of this stellar wind is so large that the wind blows a bubble into the interstellar medium (ISM). The amount of energy which is deposited into the ISM by the stellar wind during the lifetime of the
