HIGH-RESOLUTION CO OBSERVATION OF THE CARBON STAR CIT 6
Radial profiles of the 12CO J = 2–1 (left panel) and 13CO J = 2–1 (right panel) emission of the carbon star CIT6 at its systemic velocity observed by the Submillimeter Array (SMA), the Submillimeter Telescope (SMT), and combined. Results from the calculations with our radiative transfer modeling package (SPARX), as overlaid by green curves, reproduced the observed profile very well.
