Query: Three-dimensional Features of the Outer Heliosphere Due to Coupling
  between the Interstellar and Heliospheric Magnetic Field. V. The Bow Wave,
  Heliospheric Boundary Layer, Instabilities, and Magnetic Reconnection   The heliosphere is formed due to interaction between the solar wind (SW) and
local interstellar medium (LISM). The shape and position of the heliospheric
boundary, the heliopause, in space depend on the parameters of interacting
plasma flows. The interplay between the asymmetrizing effect of the
interstellar magnetic field and charge exchange between ions and neutral atoms
plays an important role in the SW-LISM interaction. By performing
three-dimensional, MHD plasma / kinetic neutral atom simulations, we determine
the width of the outer heliosheath - the LISM plasma region affected by the
presence of the heliosphere - and analyze quantitatively the distributions in
front of the heliopause. It is shown that charge exchange modifies the LISM
plasma to such extent that the contribution of a shock transition to the total
variation of plasma parameters becomes small even if the LISM velocity exceeds
the fast magnetosonic speed in the unperturbed medium. By performing adaptive
mesh refinement simulations, we show that a distinct boundary layer of
decreased plasma density and enhanced magnetic field should be observed on the
interstellar side of the heliopause. We show that this behavior is in agreement
with the plasma oscillations of increasing frequency observed by the plasma
wave instrument onboard Voyager 1. We also demonstrate that Voyager
observations in the inner heliosheath between the heliospheric termination
shock and the heliopause are consistent with dissipation of the heliospheric
magnetic field. The choice of LISM parameters in this analysis is based on the
simulations that fit observations of energetic neutral atoms performed by IBEX.
