Approximate expressions for polar gap electric field of pulsars
arXiv:astro-ph/0006256
Abstract
We derive easy-to-handle approximations for the polar gap electric field due to inertial frame dragging as derived by Harding & Muslimov 1998. A simple formula valid for polar gap height comparable to the polar cap radius is presented.
