Neutron stars are the most compact massive objects in the universe with yet unknown equation of state. During their lifetime they have violent periods during which they are primary sources for gravitational wave, x-ray and gamma-ray astronomy. We will present recent results concerning the dynamics of fast rotating neutron stars and magnetars (neutron stars with extreme magnetic fields). Our analysis suggests that the signals (electromagnetic or gravitational) during the violent phases carry information about the details of their interior, the crust, the spin period and the strength of the magnetic field.
