We present a new analysis of the dynamics of the planetary system around the pulsar B1257 + 12. A semianalytical theory of perturbation between terrestrial-mass planets B and C is developed and applied to improve the multiorbit timing formula for this object. We use numerical simulations of the pulse arrival times for PSR B1257 + 12 to demonstrate that our new timing model can serve as a tool to determine the masses of the two planets. Subject headings: celestial mechanics, stellar dynamics - planetary systems -pulsars: individual (PSR B1257 + 12).
