dc.descriptionWe studied the X-ray properties of the Hickson Compact Group HCG62, in order to determine the properties and dynamic and evolutionary state of its hot gaseous halo. Our analysis reveals that the X-ray diffuse halo has an extremely complex morphological, thermal and chemical structure. Two deep cavities, due to the presence of the AGN hosted by the central galaxy NGC 4778, are clearly visible in the group X-ray halo. The cavities appear to be surrounded by ridges of cool gas. The group shows a cool core associated with the dominant galaxy. In the outer regions the temperature structure is quite regular, while the metal abundance shows a more patchy distribution, with large Si/O and Si/Fe ratios.
