Ultracool dwarfs identified using spectra in LAMOST DR7
You-Fen Wang, A-Li Luo, Wen-Ping Chen +7
In this work, we identify 734 ultracool dwarfs with a spectral type of M6 or later, including one L0. Of this sample, 625 were studied spectroscopically for the first time. All of…
Spectral feature extraction for DB white dwarfs through machine learning applied to new discoveries in the SDSS DR12 and DR14
Xiao Kong, A-Li Luo, Xiang-Ru Li +3
Using a machine learning (ML) method, we mine DB white dwarfs (DBWDs) from the Sloan Digital Sky Survey (SDSS) Data Release (DR) 12 and DR14. The ML method consists of two parts: f…
Carbon stars identified from LAMOST DR4 using Machine Learning
Yin-Bi Li, A-Li Luo, Chang-De Du +27
In this work, we present a catalog of 2651 carbon stars from the fourth Data Release (DR4) of the Large Sky Area Multi-Object Fiber Spectroscopy Telescope (LAMOST). Using an effici…
LAMOST Spectrograph Response Curves: Stability and Application to flux calibration
Bing Du, A-Li Luo, Zhong-Rui Bai +14
The task of flux calibration for LAMOST (Large sky Area Multi-Object Spectroscopic Telescope) spectra is difficult due to many factors. For example, the lack of standard stars, fla…
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…
Eight new quasars discovered by LAMOST in one extragalactic field
Xue-Bing Wu, Zhendong Jia, Zhaoyu Chen +18
We report the discovery of eight new quasars in one extragalactic field (five degree centered at RA=, Dec=) with the LAMOST commissioning observation…
A very bright i=16.44 quasar in the `redshift desert' discovered by LAMOST
Xue-Bing Wu, Zhaoyu Chen, Zhendong Jia +18
The redshift range from 2.2 to 3, is known as the 'redshift desert' of quasars because quasars with redshift in this range have similar optical colors as normal stars and are thus…
