Detecting shock waves in non-fundamental mode RR Lyrae using large sample of spectra in SDSS and LAMOST
Xiao-Wei Duan, Xiao-Dian Chen, Li-Cai Deng +4
Steps toward the nature inside RR Lyrae variables can not only improve our understanding of variable stars but also innovate the precision when we use them as tracers to map the st…
Revisiting KELT-19Ab, WASP-156b and WASP-121b in the TESS Era
Fan Yang, Ranga-Ram Chary, Ji-Feng Liu
We present a re-analysis of transit depths of KELT-19Ab, WASP-156b, and WASP-121b, including data from the Transiting Exoplanet Survey Satellite (TESS). The large 21$\arcsec$…
Two Portions of Sagittarius Stream in the LAMOST Complete Spectroscopic Survey of Pointing Area at Southern Galactic Cap
J. K. Zhao, X. H. Ye, H. Wu +6
We constructed a sample of 13,798 stars with , log , [Fe/H], radial velocity, proper motions and parallaxes from LAMOST DR5 and Gaia DR2 in the LAMOST Complete Spect…
On the radial velocity calibrations in the LAMOST Medium-Resolution Spectroscopic Survey of Nebulae
Juan-Juan Ren, Hong Wu, Chao-Jian Wu +12
Accurate radial velocity determinations of optical emission lines (i.e. [NII]6548,6584, H, and [SII]6717,6731) are very important for investigating the kinematics and dy…
A Mysterious Ring in Dark Space?
Wei Zhang, Fan Yang, Hong Wu +10
We report the discovery of a low-surface-brightness (27.42 mag arcsec^(-2) in g band) nebula, which has a ring-like shape in the Beijing-Arizona Sky Survey (BASS). Positive detecti…
Galaxy Optical Variability of Virgo Cluster: New Tracer for Environmental Influences on Galaxies
Fan Yang, Richard J. Long, Su-Su Shan +6
We investigate the relationship between the optical variability of galaxies and their distances from the centre of the Virgo Cluster using Palomar Transient Factory data. We define…
A Catalog of Short Period Spectroscopic and Eclipsing Binaries Identified from the LAMOST & PTF Surveys
Fan Yang, Richard J. Long, Su-Su Shan +7
Binaries play key roles in determining stellar parameters and exploring stellar evolution models. We build a catalog of 88 eclipsing binaries with spectroscopic information, taking…
LAMOST Medium-Resolution Spectroscopic Survey (LAMOST-MRS): Scientific goals and survey plan
Chao Liu, Jianning Fu, Jianrong Shi +38
Since September 2018, LAMOST starts a new 5-year medium-resolution spectroscopic survey (MRS) using bright/gray nights. We present the scientific goals of LAMOST-MRS and propose a…
