Observations and modeling of gamma-ray millisecond pulsars seen with the Fermi LAT

Abstract

We present a summary of gamma-ray millisecond pulsar (MSP) observations with the Fermi Large Area Telescope. The radio and gamma-ray light curves of these MSPs have been modeled in the framework of the retarded vacuum dipole magnetic field. Likelihood fitting of the radio and gamma-ray light curves with geometric emission models allows us to give modeldependent confidence contours for the viewing geometry in these systems which are complementary to those from polarization measurements
