| Abstract: |
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. |
