摘要：

The evolved C-rich few-mass stars HR 4049 and HD 213985 present variable circumstellar extinction and emission. Observations of HR 4049 strengthen the link between the far-UV extinction rise and the presence of small C-rich particles. Variability the UV absorption bump in HD 213985 is reported here for the first time and is discussed.
