Light Curve Calculations for Triple Microlensing Systems
Renkun Kuang, Shude Mao, Tianshu Wang +2
We present a method to compute the magnification of a finite source star lensed by a triple lens system based on the image boundary (contour integration) method. We describe a new…
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…
Measuring the local dark matter density with LAMOST DR5 and Gaia DR2
Rui Guo, Chao Liu, Shude Mao +3
We apply the vertical Jeans equation to the kinematics of Milky Way stars in the solar neighbourhood to measure the local dark matter density. More than 90,000 G- and K-type dwarf…
A discrete chemo-dynamical model of M87's globular clusters: Kinematics extending to ~ 400 kpc
Chao Li, Ling Zhu, R. J. Long +14
We study the mass distribution and kinematics of the giant elliptical galaxy M87 (NGC 4486) using discrete chemo-dynamical, axisymmetric Jeans equation modelling. Our catalogue com…
SDSS-IV MaNGA: Internal mass distributions and orbital structures of early-type galaxies and their dependence on environment
Yunpeng Jin, Ling Zhu, R. J. Long +3
In our earlier 2019 paper, we evaluated the reliability of Schwarzschild's orbit-superposition dynamical modelling method in estimating the internal mass distribution, intrinsic st…
