Abstract  We calculate the light curve and phase-resolved spectra of Geminga in a three-dimensional pulsar magnetosphere model. The light curve of gamma-rays is consistent with that observed if the magnetic inclination and viewing angle are ~50° and ~86° respectively. We also model the phase-resolved spectra of the Geminga pulsar.
Keywords:  Geminga pulsar      $\gamma$-ray light curve      phase-resolved spectra
