Distances to the bow shock of the ISW and the stellar wind interaction in the debris ring mid-plane. The distances were obtained using Eq. (11) with θ = 90° for the ISW parameters giving the observed shape morphology for the dust particles with (see Fig. 4). Calculated distances to the bow shock are significantly smaller than the stellocentric distances 55−65 AU at which the bulk of the debris ring ejecting the dust particles is located. Therefore, the debris ring should not be located in the bow shock. Since, the termination shock of the stellar wind is closer to the star than the bow shock, the dynamics of dust particles should not be affected by the stellar wind.
