Self-oscillations of the tube-like astrosphere: new type of instability

Video files complement the main paper, which discusses the instability of astrospheric jets around stars with strong intrinsic magnetic fields. "Video-1.avi" corresponds to the 2D flow shown in Figure 2 (Panel A), where the interstellar medium is at rest, $M_A$ = 8, $\chi$ = 4. "Video-2.avi" corresponds to the 3D flow shown in Figure 4, with the interstellar medium also at rest and $M_A$ = 3, $\chi$ = 4.
