Possible observations of Vega-like stars by the ASTRO-F and the HII/L2 3.5m space telescope are proposed. Vega-like stars are main sequence stars with mid-infrared and/or far-infrared excess. A few of these stars have been observed precisely at various wavelengths and it was found out that they tend to have hot (～300K) circumstellar dust like the zodiacal dust in our solar system and warm (～50K) dust ring around 30{50 AU from the central star. In spite of thesediscoveries, one question still remains; How many Vega-like stars are there? Mid- and far-infrared surveys by the ASTRO-F and the HII/L2 telescope will be the best ones to get the answer to this question. The ASTRO-F/FIS survey could detect `α Lyr' located at a distance of <50pc, within which roughly 150 of A-type main sequence stars exist. The HII/L2 3.5m telescope survey has the capability to detect much farther, up to 100pc. Thus, the total number of candidates will increase to as many as ～1000. |
