AESTRA II: Generative Spectral Modeling of the Sun as a Star for Precise Radial Velocities
Yan Liang, Joshua N. Winn, Peter Melchior +2
The detection of Earth analogs with extreme-precision radial velocities (EPRVs) is limited by spectral variability from stellar activity, telluric absorption, and instrumental syst…

The Impact of Orbital Anisotropy Assumptions in Lensing-Dynamics Modeling
Yan Liang, Dandan Xu, Anowar J. Shajib +2
We investigate potential systematic biases introduced by assumptions regarding stellar orbital anisotropy in joint lensing-dynamics modeling. Our study employs the massive early-ty…
