LTD064402+245919: A Subgiant with a 1-3 M Undetected Companion Identified from LAMOST-TD Data
Fan Yang, Bo Zhang, Richard J. Long +11
Single-line spectroscopic binaries recently contribute to the stellar-mass black hole discovery, independently of the X-ray transient method. We report the identification of a sing…
SDSS-IV MaNGA: Stellar M/L gradients and the M/L-colour relation in galaxies
Junqiang Ge, Shude Mao, Youjun Lu +3
The stellar mass-to-light ratio gradient in SDSS band of a galaxy depends on its mass assembly history, which is imprinted in its morphology and gradients of…
An Empirical Bayesian Approach to Limb-darkening in Modeling WASP-121b Transit Light Curves
Fan Yang, Richard J. Long, Ji-Feng Liu +6
We present a novel, iterative method using an empirical Bayesian approach for modeling the limb darkened WASP-121b transit from the TESS light curve. Our method is motivated by the…
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…
Stellar Dynamical Modeling - Accuracy of 3D Density Estimation for Edge-on Axisymmetric Galaxies
Richard J. Long, Shengdong Lu, Dandan Xu
From Rybicki's analysis using the Fourier slice theorem, mathematically it is possible to reproduce uniquely an edge-on axisymmetric galaxy's 3D light distribution from its 2D surf…
