Close-up images of the region of interaction of the interplanetary magnetic field and that of Proxima b. The top panels highlight the effect of the tilt angle (15° and 37° for the left and right panels, respectively, for a fixed value of B_p = 0.32 G. The bottom panels show the effect of the planetary magnetic field on the reconnection region (0.32 G and 1.28 G for the left and right panels, for a fixed tilt of 23.5°). The interaction region is clearly farther away from the planet for the case of B_p = 1.28 G. The reconnection region (in pink) is defined as the region where the local magnetic field is ≤0.32 mG, corresponding to seven times the normalized magnetic field value in our simulations. The planet Proxima b is shown as a black circle.
