Context. We performed a mid-infrared imaging survey of evolved stars in order to study the dust distribution in circumstellar env elopes around these objects and to better understand the mass-loss mechanism responsible for the formation of these envelopes. During this survey, we resolved for the first time the circumstellar envi ronment of IRAS 17163-3907 (hereinafter IRAS17163), which is one of the brightest objects in the mid-infrared sky, but is surpri singly not well studied. Aims. Our aim… Expand
