Аннотация:We discuss possible existence of a magnetodisk around the exoplanet HAT–P–11b. We used availableobservations to determine properties of the exoplanet and the stellar wind passing by it and obtained arough estimate of the size of the planet’s magnetosphere. Comparing our estimate to published results ofcomputations in a 3D electromagnetic relativistic and collisionless particle-in-cell model of the magnetosphere,we found a discrepancy in the magnetosphere size estimated using these two techniques. A possibleinterpretation of the discrepancy is suggested.
