X-ray emission from magnetic dissipation in the magnetar magnetosphere
چکیده انگلیسی

Magnetic dissipation through decay of Alfvén waves in the magnetar magnetosphere is discussed. Transport of magnetic fields in the star leads to dissipation of the magnetic energy through either direct internal heating or transferring of the energy in waves that decay in the magnetar magnetosphere. In the latter case, the Alfvén waves are excited by crust dislocations or elastic waves underneath the star’s surface. It is suggested that these Alfvén waves can decay into ion sound waves which can be effectively damped leading to strong plasma heating. Hot plasmas expand producing transient X-rays.
