Abstract
We report on the discovery of 100 MeV ³-rays from the binary system PSR B125963/LS 2883 using the Large Area Telescope (LAT) on board Fermi. The system comprises a radio pulsar in orbit around a Be star. We report on LAT observations from near apastron to <128 days after the time of periastron, tp , on 2010 December 15. No ³-ray emission was detected from this source when it was far from periastron. Faint ³-ray emission appeared as the pulsar approached periastron. At
