Cím: Why do millisecond pulsars have weaker magnetic fields compared to 
ordinary pulsars?

Abstract
Recently, we have proposed a model for the screening of the magnetic 
field of an accreting neutron star by the accreted material flowing from 
the polar regions towards the equator and sinking there underneath the 
surface. In this earlier model, it was assumed that the flow pattern 
remained stationary over time. However, as the surface magnetic field 
weakens, the accretion takes place over a wider region around the pole, 
making the flow more radial and isotropic. In the present work, we extend 
this two-dimensional model to include the time dependence of the flow of 
the accreted material.
