Pulsar death line revisited – II. ‘The death valley’

In this paper, which is the second in a series of papers, we analyse what parameters can determine width radio pulsar 'death valley' $P$-${\dot P}$ diagram. Using exact expression for maximum potential drop, be realised over magnetic polar caps and corresponding threshold secondary plasma production determined Paper I, detail observed distribution pulsars taking into account all possible (radius $R$ moment inertia neutron star $I_{\rm r}$, high-energy tail $\gamma$-quanta energy giving rise to particles, etc.) could broaden 'the death line'. We show that consistent allowance these effects leads sufficiently wide containing even dipole field star.
