Abstract
We have made far-infrared mapping observations around a heavily mass losing evolved star IRC—10529 with ISO. It is found that IRC—10529 shows a very compact circumstellar dust envelope in the 60 and 90 μm images 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 stage of AGB evolution with an extremely high mass-loss rate very recently.
