Upper Limits on GeV Gamma-Ray Flux from the Ultra-long Period Neutron Star PSR J0901-4046.

DUERR A., FLEISCHHACK H. and KIEDA D.

Abstract (from CDS):

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.
