Population synthesis of isolated Neutron Stars with magneto--rotational evolution

Understand

We revisit the population synthesis of isolated radio-pulsars incorporating recent advances on the evolution of the magnetic field and the angle between the magnetic and rotational axes from new simulations of the magneto-thermal evolution and magnetosphere models, respectively.

• An interesting novelty in our approach is that we do not assume the existence of a death line.
• We discuss regions in parameter space that are more consistent with the observational data.
• In particular, we find that any broad distribution of birth spin periods with $P_0\lesssim 0.5$ s can fit the data, and that if the alignment angle is allowed to vary consistently with the torque model, realistic magnetospheric models are favoured compared to models with classical magneto-dipolar radiation losses.
