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…
