Imaging of detached shells around the carbon stars


We present the first optical images of scattered light from large, detached gas/dust shells around two carbon stars, R Scl and U Ant, obtained in narrow band filters centred on the resonance lines of neutral K and Na, and in a Strömgren b filter (only U Ant). They confirm results obtained in CO radio line observations, but also reveal new and interesting… (More)
