Abstract:

Neutron stars are compact remnants of supernova explosions. They have radii of 11-13 km

and masses comparable to that of the sun. One could expect neutron stars to be quiet, dead

remnants of stellar evolution. Instead, they happen to produce most spectacular, extreme

radiative phenomena. This talk will give a broad overview of neutron star activity and recent

progress in understanding its mechanisms. Neutron stars generate powerful beams of coherent

radio waves, pulsed high-energy gamma-rays, relativistic electron-positron winds, and giant

X-ray flares. Some neutron stars live in binary systems and eventually merge, emitting strong

gravitational waves and creating explosions observed from cosmological distances. Recent

observational discoveries will be discussed, including the exciting detection of gravitational

waves from a neutron star merger and its electromagnetic counterpart.
