Abstract
We have made far-infrared mapping observations around a heavily mass l osing evolved star IRC-10529 with ISO. It is found that IRC -10529 sho ws a very compact circumstellar dust envelope in the 60 and 90 mu m im ages obtained by ISOPHOT. Such a small size of the circumstellar dust envelope indicates very short history of the present strong mass loss. It is very likely that IRC-10529 has just evolved into the final stag e of AGE evolution with an extremely high mass-loss rate very recently .
