Three-dimensional MHD simulation of 55 Cnc. Wind velocity is shown as a slice at the z = 0 plane and extends to 30 R_⋆. The Alfvén surface is shown in orange; its intersection with the orbital plane of the planets is highlighted with a thick black line. Open magnetic field lines are shown in grey and closed magnetic field lines are shown in red. The orbits of 55 Cnc e and bare represented in black and white respectively. figure.1figure
