Based on the available data on the magnetic field of the star HAT-P-11 and its closest exoplanet HAT-P-11b, as well as information on the stellar wind in this system, we construct the HAT-P-11b magnetic field magnetospheric model. We show how the value and orientation of the interplanetary magnetic field control the magnetospheric structure. Each component of the stellar wind’s magnetic field creates a specific type of reconnection with the exoplanet’s magnetic field.

2. Fig. 1. Magnetosphere of the exoplanet HAT-P-11b for zero IMF in the noon-midnight section. The model parameters are given in the text of the article, the magnetic moment of the exoplanet is directed to the north. Solid lines show magnetic field lines; dashed line shows magnetopause. The exoplanet is marked with a circle. X and Z coordinates are plotted along the horizontal and vertical axes.
