The work considers the process of collision of two neutron stars with the formation of spinar. The approximate model includes four main forces controlling the process of spinar collapse, namely: the gravitational force, the pressure of nuclear matter and thermal pressure, the centrifugal force, and the dissipative force due to the presence of a magnetic field. Taken into account: the effect of entrapment of the frame of reference, the disappearance of the magnetic field, as well as the gravitational red shift and time dilation. In addition, the effect of neutrino cooling is calculated. Separately, the paper considers the transition from the model of two separate converging objects to the spinar model. This transition is made so that the main parameters (density, momentum, speed, and some others) undergo the smallest jump. The change in mass during the fusion process is calculated approximately. Two main situations were considered: the fusion of two light neutron stars followed by the formation of a heavy neutron star, and the fusion of two neutron stars with a total mass greater than Oppenheimer-Volkov mass followed by the formation of a black hole. The main result of the simulation is the dependence of spinar energy release on time. The distribution of this energy over the ranges of electromagnetic radiation is calculated under natural assumptions. The result is a theoretical spinar luminosity at the moment of collapse for different distances, masses and magnetic fields
