The high spin-down luminosity of the pulsar and the plerionic feature around the pulsar observed with radio and X-rays suggest that VHE gamma-ray emission is quite likely above the sensitivity of the CANGAROO telescope. The CANGAROO results on other pulsars, such as PSR1259-63, are also presented. PSR1259-63 is a highly eccentric X-ray binary system, which includes a high mass Be companion star, and a preliminary analysis on the data taken 4 months after the periastron in 1994 suggests emission of VHE gamma rays.", "revisions": [ { "version": "v1", "updated": "1997-07-02T02:14:47.000Z" } ], "analyses": { "keywords": [ "observations", "highly eccentric x-ray binary system", "vhe gamma rays", "young gamma-ray pulsar", "8m cerenkov imaging telescope" ], "note": { "typesetting": "LaTeX", "pages": 4, "language": "en", "license": "arXiv", "status": "editable", "inspire": 445534 } } }
