The Magnetar Connection

We investigate the combined evolution of the dipolar surface magnetic field (B _s ) and the spin-period (P _s ) of known Magnetars and high magnetic field ( $${{{B}}_s} \mathbin{\lower.3ex\hbox{$\buildrel>\over {\smash{\scriptstyle∼}\vphantom{_x}}$}} {10^{13}}{{G}}$$ ) radio pulsars. We study the long term behaviour of these objects assuming a simple Ohmic dissipation of the magnetic field. Identifying the regions (in the P _s -B _s plane) in which these neutron stars would likely move into, before crossing the death-line to enter the pulsar graveyard, we comment upon the possible connection between the Magnetars and other classes of neutron stars.
