Radial velocity variability caused by stellar active regions challenges the discovery and characterization of Earth-like exoplanets and complicates the interpretation of real planetary signals. However, the spurious radial velocities caused by the presence of active regions on the star depend on wavelength and they can be helpful to understand which ...
