viper: High-precision radial velocities from the optical to the infrared (Reaching 3 m/s in the K band of CRIRES+ with telluric modelling)
J. Köhler, M. Zechmeister, A. Hatzes +18
In recent years, a number of new instruments and data reduction pipelines have been developed to obtain high-precision radial velocities (RVs). In particular in the optical, consid…

Stellar parameter prediction and spectral simulation using machine learning
VojtÄch CvrÄek, Martino Romaniello, Radim Šára +2
We applied machine learning to the entire data history of ESO's High Accuracy Radial Velocity Planet Searcher (HARPS) instrument. Our primary goal was to recover the physical prope…
