Configurations of the solar wind flow and magnetic field around the planets with no magnetic field : calculation by a new MHD simulation scheme

摘要: A new MHD simulation scheme is developed on an unstructured grid system using the finite volume total variation diminishing and applied to problem of solar wind-planet interaction, assuming a perfect-conducting ionosphere around planet. It shown that presented here enables one calculate effectively configuration three-dimensional flow near planets, together with draping process magnetic field. Results calculation give general confirmation for formations bow shock, barrier, magnetosheath, magnetopause, wake region, plasma sheet, magnetotail. Because J × B forces, planet accelerated in polar regions decelerated equatorial plane wind velocity field (VB) coordinate system. In tail forces act accelerate midnight meridian suppress formation trailing shock. However, present gives weaker magnitude than given by observations suggests role some additional mechanisms pileup tail.
