Stellar activity due to different processes (magnetic activity, photospheric flows) affects the measurement of radial velocities (RV). Radial velocities have been widely used to detect exoplanets, although the stellar signal significantly impacts the detection and characterisation performance, especially for low mass planets. On the other hand, RV time series are also very rich in information on stellar processes. In this lecture, I review the context of RV observations, describe how radial velocities are measured, and the properties of typical observations. I present the challenges represented by stellar activity for exoplanet studies, and describe the processes at play. Finally, I review the approaches which have been developed, including observations and simulations, as well as solar and stellar comparisons.

Measuring the Suns radial velocity variability due to supergranulation over a magnetic cycle
Using eight years of HARPS-N Sun-as-a-star radial velocities, the authors measure a clear variation in the supergranulation timescale over the solar cycle, strongly anti-correlated with the sunspot number.

Constraining nearby substellar companion architectures using High Contrast Imaging, Radial Velocity and Astrometry data
For seven nearby M dwarfs, combining imaging, radial velocity, and astrometry raises the fraction of detectable substellar companions beyond any single method, though no new companions were found.
