The angular resolution of ~0.06 degree (for events triggering 3 or 4 telescopes) and the large field of view of H.E.S.S. ($5^{\circ}$ diameter) are well adapted to studying the morphology of the object in very high energy gamma-rays, which exhibits a remarkably thin shell very similar to the features observed in the radio range and in X-rays. The spectral analysis of the source from 300 GeV to 20 TeV is also presented. Finally, the possible origins of the very high energy gamma-ray emission (Inverse Compton scattering by electrons or the decay of neutral pions produced by proton interactions) are discussed, on the basis of morphological and spectral features obtained at different wavelengths. %G English %Z HESS %L in2p3-00124615 %U https://in2p3.hal.science/in2p3-00124615 %~ IN2P3 %~ OBSPM %~ CEA %~ INSU %~ METEO %~ UNIV-PARIS7 %~ X %~ UNIV-SAVOIE %~ UPMC %~ UNIV-TLSE3 %~ UGA %~ LPTA %~ LAPP %~ LLR %~ LPNHE %~ APC %~ CNRS %~ UNIV-GRENOBLE1 %~ UNIV-MONTP2 %~ CNES %~ OSUG %~ LUTH %~ OMP %~ OMP-CESR %~ X-LLR %~ LAOG %~ X-DEP %~ X-DEP-PHYS %~ DSM-IRFU %~ IRFU-APC %~ PSL %~ UPMC_POLE_2 %~ UNIV-MONTPELLIER %~ CEA-DRF %~ SORBONNE-UNIVERSITE %~ SU-SCIENCES %~ UNIV-PARIS %~ UP-SCIENCES %~ OBSPM-PSL %~ USMB-COMUE %~ SU-TI %~ ALLIANCE-SU %~ UNIV-UT3 %~ UT3-INP %~ UT3-TOULOUSEINP %~ UM1-UM2 %~ LPNHE-2 %~ TEST-SEBASTIEN3
