The far-infrared (IRAS) excess in luminous F-G stars.
Abstract
The far-infrared IRAS excesses are found in ten luminous F-G stars. The far-IR fluxes from these stars are due to large amounts of dust around them. The far-IR flux distribution, far-IR luminosities and dust masses are similar to those in observed planetary nebulae. The mass of the dust around HD 187885 and HD 179821 is of the order of 10-2M_sun;. These ten stars may be in the AGB - post-AGB stage of evolution.
