Scientific paper

As a result of IRAS observations, main-sequence stars that have circumstellar debris disks and thus show infrared excess have been discovered. Since debris disks are thought to be the final stage of planet formation, it is very important to investigate the properties and evolution of debris disks statistically. Especially, mid-infrared observations become a key method for planet formation study because mid-infrared excess traces the thermal emission from debris dust in planetforming regions. We are carrying on an unbiased survey of debris disk candidates that show mid-infrared excess by using the AKARI/IRC mid-infrared all-sky survey data. So far, we have identified seven new debris disk candidates that show large 18 μm excess. Here, we present the initial results of the debris disk survey.
