AbstractSince the release of the Large Sky Area Multi-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 μm excess candidates. In this paper, we present 10 FGK candidates which show an excess in the infrared at 22 μm. All the 10 sources are newly identified 22 μm 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 μm band and three candidates even show excess from 3.4 μm. To characterize the amount of dust, we also estimate the fractional luminosity of 10 22 μm excess candidates.
