Description
Abstract: The interplay of a strong gravitational field (where GR effects cannot be neglected), a strong magnetic field (above the threshold for vacuum polarization) and fast rotation (up to kHz) make neutron stars some the most fascinating objects in the high-energy universe. But is also make the correct and physically realistic description of their phenomenology extremely challenging, such that even today, 50 years after their discovery, they are at the forefront of many different fields of modern physics. I will present recent developments of self-consitent, realistic models of strongly magnetized NS, and the mathematical and numerical framework developed to handle simultaneously general relativity and MHD fluid dynamics. The result will be discussed, with a focus on GRB, GW emission and QED effects in Magnetars.
