Searching for Magnetic White Dwarfs in LAMOST DR10
Si-Cheng Yu, Juan-Juan Ren, Vitaly V. Neustroev +7
Magnetic white dwarfs (MWDs) are key to understanding the origin and evolution of magnetic fields in compact stars. While large spectroscopic surveys such as SDSS have greatly expa…
All-sky Guide Star Catalog for CSST
Hui-Mei Feng, Zi-Huang Cao, Man I Lam +17
The China Space Station Telescope (CSST) is a two-meter space telescope with multiple back-end instruments. The Fine Guidance Sensor (FGS) is an essential subsystem of the CSST Pre…
Insight-HXMT observations of Swift J0243.6+6124: the evolution of RMS pulse fractions at super-Eddington luminosity
P. J. Wang, L. D. Kong, S. Zhang +116
Based on Insight-HXMT data, we report on the pulse fraction evolution during the 2017-2018 outburst of the newly discovered first Galactic ultraluminous X-ray source (ULX) Swift J0…
New Oe stars in LAMOST DR5
Guang-Wei Li, Jian-Rong Shi, Brian Yanny +7
Stars of spectral type Oe are very rare. To date, only 13 Oe stars have been identified within our Galaxy. In this paper, we present six new Oe stars and four new B0e stars found i…
Cosmic Ray Removal in Fiber Spectroscopic Image
Zhongrui Bai, Haotong Zhang, Hailong Yuan +4
Single-exposure spectra in large spectral surveys are valuable for time domain studies such as stellar variability, but there is no available method to eliminate cosmic rays for si…
Sky Subtraction for LAMOST
Zhong-Rui Bai, Hao-Tong Zhang, Hai-Long Yuan +7
Sky subtraction is the key technique in data reduction of multi-fiber spectra. Knowledge of the related instrument character is necessary to determine the method adopted in sky sub…
Candidate members of the Pal 5, GD-1, Cetus Polar, and Orphan tidal stellar halo streams from Sdss DR9, Lamost DR3 and APOGEE catalogues
Guang-Wei Li, Brian Yanny, Hao-Tong Zhang +8
We present candidate members of the Pal 5, GD-1, Cetus Polar, and Orphan tidal stellar streams found in LAMOST DR3, SDSS DR9 and APOGEE catalogs. In LAMOST DR3, we find 20, 4, 24 h…
LAMOST Spectroscopic Survey of the Galactic Anti-centre (LSS-GAC): target selection and the first release of value-added catalogues
Haibo Yuan, Xiaowei Liu, Zhiying Huo +16
As a major component of the LAMOST Galactic surveys, the LAMOST Spectroscopic Survey of the Galactic Anti-centre (LSS-GAC) aims to survey a significant volume of the Galactic thin/…
ASERA: A Spectrum Eye Recognition Assistant for Quasar Spectra
Hailong Yuan, Haotong Zhang, Yanxia Zhang +3
Spectral type recognition is an important and fundamental step of large sky survey projects in the data reduction for further scientific research, like parameter measurement and st…
The properties of cross-correlation and spectra of the low-mass X-ray binary 4U 1608-52
Ya-Juan Lei, Shu Zhang, Jin-Lu Qu +4
With {\it RXTE} data, we analyzed the cross-correlation function between the soft and hard X-rays of the transient atoll source 4U 1608-52. We found anti-correlations in three outb…
Moon night sky brightness simulation for Xinglong station
Song Yao, Hao-Tong Zhang, Hai-Long Yuan +5
With a sky brightness monitor in Xinglong station of National Astronomical Observatories of China (NAOC), we collected data from 22 dark clear nights and 90 lunar nights. We first…
Evolution of cross-correlation and time lag of 4U 1735-44 along the branches
Ya-Juan Lei, Hao-Tong Zhang, Cheng-Min Zhang +7
We analyze the cross-correlation function between the soft and hard X-rays of atoll source 4U 1735-44 with RXTE data, and find the anti-correlated soft and hard time lags of about…
