Description
Estimating precise radial velocities due to orbiting exoplanets in the presence of stellar activity is a challenging statistical problem. As instrumentation continues to improve, allowing for the detection of sub meter-per-second shifts, the effect of stellar activity becomes more problematic because the stellar activity can cause distortions in the spectra that mimic the RV of an orbiting exoplanet potentially leading to false detections. In this review, I will discuss various statistical methods that have been developed to address this issue, and suggest some additional routes forward.
