Upper Limits on GeV Gamma-Ray Flux from the Ultra-long Period Neutron Star PSR J0901−4046
Abstract PSR J0901−4046 is a radio neutron star with an ultra-long spin period of 75.88 s. We search 14 yr of Fermi-LAT observations for evidence of steady gamma-ray emission. We find no evidence of gamma-ray emission and set a 95% upper limit on the flux from PSR J0901−4046 of 1.4 × 10 −9 photons cm −2 s −1 assuming a power law with exponential cutoff spectrum.
