Title AKARI/IRC 18 micron survey of warm debris disks
Abstract After the 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 property and evolution of debris disks statistically. However, little is known about the properties of the warm (Tdust > 150 K) debris disk material located close to stars, which is likely to have a more direct link to the formation of terrestrial planets than the low temperature debris dust which has been detected to date. Mid-infrared (MIR) observations become a key method for planet formation study since MIR excess traces the thermal emission from debris dust in inner planet forming region. We are carrying on an survey of warm debris disks that show MIR excess by using the AKARI/IRC MIR All-Sky Survey data, which is separately presented by Ishihara et al. So far, we have identified several new debris disk candidates that show large 18 micron excess. In this presentation, we will show the recent results of the debris disk survey with the AKARI/IRC MIR All-Sky Survey data.
