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

Optical/near-infrared observations of the Fried Egg Nebula: Multiple shell ejections on a 100 yr timescale from a massive yellow hypergiant
Context. The fate of a massive star during the latest stages of its evolution is highly dependent on its mass-loss rate/geometry and therefore knowing the geometry of the circumstellar material closeExpand

The dusty aftermath of SN Hunt 248: merger-burst remnant?
SN Hunt 248 was classified as a non-terminal eruption (a supernova ‘impostor’) from a directly identified and highly variable cool hypergiant star. The 2014 outburst achieved peak luminosityExpand
A massive parsec-scale dust ring nebula around the yellow hypergiant Hen 3-1379
