IGRINS RV: A Python Package for Precision Radial Velocities with Near-Infrared Spectra
Abstract
The relative radial velocity of a star with respect to the Sun can be calculated from its electromagnetic spectrum using the Doppler Effect. This line-of-sight motion, called the Radial Velocity (RV), is an essential tool for astrophysicists. RVs are not only used to detect and characterize exoplanets, but also play a key role in studies of binary stars, star clusters, and moving group member identification.
