H I Free-Bound Emission of Planetary Nebulae with Large Abundance Discrepancies: Two-Component Models versus Kappa-distributed electrons
Yong Zhang, Xiao-Wei Liu, Bing Zhang
The "abundance discrepancy" problem in the study of planetary nebulae (PNe), viz., the problem concerning systematically higher heavy-element abundances derived from optical recomb…
Substructure in bulk velocities of Milky Way disk stars
Jeffrey L. Carlin, James DeLaunay, Heidi Jo Newberg +11
We find that Galactic disk stars near the anticenter exhibit velocity asymmetries in both the Galactocentric radial and vertical components across the mid-plane as well as azimutha…
Hunting for Extremely Faint Planetary Nebulae in the SDSS Spectroscopic Database
Haibo Yuan, Xiaowei Liu
Using ~1,700,000 target- and sky-fiber spectra from the SDSS, we have carried out a systematic search for Galactic planetary nebulae (PNe) via detections of the [OIII] 4959, 5007 l…
LSS-GAC - A LAMOST Spectroscopic Survey of the Galactic Anti-center
X. -W. Liu, H. -B. Yuan, Z. -Y. Huo +10
As a major component of the LAMOST Galactic surveys, the LAMOST Spectroscopic Survey of the Galactic Anti-center (LSS-GAC) will survey a significant volume of the Galactic thin/thi…
The LAMOST Survey of Background Quasars in the Vicinity of the Andromeda and Triangulum Galaxies -- II. Results from the Commissioning Observations and the Pilot Surveys
Zhi-Ying Huo, Xiao-Wei Liu, Mao-Sheng Xiang +68
We present new quasars discovered in the vicinity of the Andromeda and Triangulum galaxies with the LAMOST during the 2010 and 2011 observational seasons. Quasar candidates are sel…
Empirical extinction coefficients for the GALEX, SDSS, 2MASS and WISE passbands
Hai-Bo Yuan, Xiao-Wei Liu, Mao-Sheng Xiang
Using the "standard pair" technique of paring stars of almost nil and high extinction but otherwise of almost identical stellar parameters from the SDSS, and combing the SDSS, GALE…
