【 摘 要 】

It is well known that the Interstellar Boundary Explorer (IBEX) discovered a region of enhanced energetic neutral atom (ENA) emission seen in all-sky maps as a ribbon. The enhanced fluxes of ENAs were between 2 and 3 times greater than adjacent regions of the sky. The ribbon itself was not predicted by any models of the heliosphere interface. In the paper by Ratkiewicz, Strumik and Grygorczuk published in the Astrophysical Journal, 756:3, 2012 the authors presented some arguments to show that it was possible to predict the IBEX ribbon. In the current paper the numerical results obtained by three-dimensional MHD simulations of the interaction between the solar wind and interstellar medium by Ratkiewicz et al. [2012] are summarized. Some new aspects of this issue are discussed.
