MeV to TeV Gamma-Ray Observations of PSR 1957+20
Abstract
Observational data are analyzed to search for the presence of a gamma-ray signal from the direction of the eclipsing binary pulsar PSR 1957 + 20. Indications for possible excess emission are found at the predicted phase of the fourth Lagrangian point (L4). The most reasonable origin for 50 MeV to 3 TeV radiation from L4 appears to be pi(0) decay from proton collisions in 'Trojan matter' following the acceleration of protons in a shock front close to L4.
