Query: FGK 22 $\mu$m Excess Stars in LAMOST DR2 Stellar Catalog   Since the release of LAMOST (the Large Sky Area Multi-Object Fiber
Spectroscopic Telescope) catalog, we have the opportunity to use the LAMOST DR2
stellar catalog and \emph{WISE All-sky catalog} to search for 22 $\mu$m excess
candidates. In this paper, we present 10 FGK candidates which show an excess in
the infrared (IR) at 22 $\mu$m. The ten sources are all the newly identified 22
$\mu$m excess candidates. Of these 10 stars, 5 stars are F type and 5 stars are
G type. The criterion for selecting candidates is $K_s-[22]_{\mu m}\geq0.387$.
In addition, we present the spectral energy distributions (SEDs) covering
wavelength from optical to mid-infrared band. Most of them show an obvious
excess from 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 ten 22 $\mu$m excess candidates.
