LAT detection <strong>of</strong> PSR B1509-58(Abdo et al., 2010, ApJ, accepted, arXiv:1003.3833)• Detection <strong>of</strong> PSR B1509-58 at 4.5 σ level above 30 MeV• No pulsed signal detected above 1 GeV• Second peak at 0.34±0.02 almost aligned with COMPTEL• First peak at 0.96 ± 0.02 (not detected by COMPTEL) : harder component ?• Spectral energy distribution : consistent with the break at a few tens <strong>of</strong>MeV as described by Kuiper et al.
