Interaction of Low-Activity Comets with the Solar Wind
TLDR
In this article, the solar wind flow around a cometary atmosphere is calculated using the three-dimensional magnetohydrodynamic model developed by the authors, and the behavior of the flowfield and the magnetic field disturbed by the cometary outflow is analyzed.Abstract:
The solar wind flow around a cometary atmosphere is calculated using the three-dimensional magnetohydrodynamic model developed by the authors. Emphasis is placed on the case of low-activity comets in which some special features, both quantitative and qualitative, are inherent. The behavior of the flowfield and the magnetic field disturbed by the cometary outflow is analyzed. Some similarity laws that govern the pattern of the interaction between the solar wind and a cometary atmosphere are derived on the basis of the calculated results.read more

Influence of the magnetic field on the density distribution of solar wind protons and cometary ions in the shock layer ahead of cometary ionospheres
TL;DR: In this paper, the density distributions of solar wind protons and cometary ions between the bow shock and the cometary ionopause (in the shock layer) were obtained for the Giotto spacecraft under the conditions of flow around Comets Halley and Grigg-Skjellerup.

Revisiting the Single-Fluid Modeling of the Solar Wind-Comet Interaction: Closer Look at the Cometosheath
TL;DR: In this paper, a single fluid gas-dynamic model of solar wind-comet ionosphere interaction is applied to reveal some specifics in the morphology of the shocked “contaminated” solar wind region (cometosheath).

A multi-state HLL approximate Riemann solver for ideal magnetohydrodynamics
Takahiro Miyoshi,Kanya Kusano +1 more
TL;DR: In this paper, a multi-state Harten-Lax-van Leer (HLL) approximate Riemann solver for the ideal magnetohydrodynamic (MHD) equations is developed based on the assumption that the normal velocity is constant over the riemann fan.

Three‐dimensional multiscale MHD model of cometary plasma environments
TL;DR: In this article, a multiscale adaptive up-wind scheme for MHD (MAUS-MHD) was proposed. But the model is not suitable for the case of a single comet.
