The star LS 5039 is a new microquasar system with apparent persistent ejection of relativistic plasma at a 3 kiloparsec distance from the sun. It may also be associated with a gamma-ray source discovered by the Energetic Gamma Ray Experiment Telescope (EGRET) on board the COMPTON-Gamma Ray Observatory satellite. Before the discovery of LS 5039, merely a handful of microquasars had been identified in the Galaxy, and none of them was detected in high-energy gamma-rays.13 p.application/pdfeng(c) Paredes i Poy, Josep Maria et al., 2000Estels binaris de raigs XQuàsarsRaigs gammaAstronomia de raigs gammaAstrofísicaX-ray binariesQuasarsGamma raysGamma ray astronomyAstrophysicsinfo:eu-repo/semantics/article1712472013-08-27info:eu-repo/semantics/openAccess
