| 英文摘要 | Since the release of the Large Sky AreaMulti-Object Fiber Spectroscopic Telescope (LAMOST) catalog, we have had the opportunity to use the LAMOST DR2 stellar catalog and the WISE All-Sky Data Release catalog to search for 22 mu m excess candidates. In this paper, we present 10 FGK candidates which show an excess in the infrared at 22 mu m. All the 10 sources are newly identified 22 mu m excess candidates. Of these 10 stars, five stars are F type and five stars are G type. The criterion for selecting candidates is K-s - [22] >= 0.387. In addition, we present the spectral energy distributions covering wavelengths from the optical to mid-infrared band. Most of them show an obvious excess from the 12 mu m band and three candidates even show excess from 3.4 mu m. To characterize the amount of dust, we also estimate the fractional luminosity of 10 22 mu m excess candidates. |
