摘要：

We present observations of dust-scattered light of the carbon stars U Ant, R Scl, and U Cam taken with the EFOSC2 camera on the ESO 3.6-m telescope and the ACS on the Hubble Space Telescope. The observations show the detached shells around these stars in unprecedented detail, revealing a distinctively clumpy structure in the HST images of R Scl, and a separation of the dust and gas in the ground-based data for U Ant. This allows us to investigate the detached shells and their origin with exceptional precision.
