Gaia Calibrated UV Luminous Stars in LAMOST
  We take advantage of the Gaia data release 2 to present 275 and 1,774
ultraviolet luminous stars in the FUV and the NUV. These stars are 5$\sigma$
exceeding the centers of the reference frame that is built with over one
million UV stars in the log $g$ vs $T_\textrm{eff}$ diagram. The Galactic
extinction is corrected with the 3D dusty map. In order to limit the
Lutz-Kelker effect to an insignificant level, we select the stars with the
relative uncertainties of the luminosity less than 40% and the trigonometric
parallaxes less than 20%. We cross-identified our sample with the catalogs of
RR Lyr stars and possible white dwarf main-sequence binaries, and find they
compose $\sim$ 62% and $\sim$ 16% of our sample in the FUV and NUV,
respectively. This catalog provides a unique sample to study stellar activity,
spectrally unresolved compact main-sequence binaries and variable stars.
