Introduction: The Hunt for Extra-Solar Planets,ades, developments in instrumentation and observation techniques have led to revolutionary discoveries: we now know that planets revolving around other stars than our Sun exist, and better still, they appear to be very common.

Stellar Activity as a Source of Radial-Velocity Variability, variability. This chapter provides a review of the manifestations of magnetic activity, their impact on photometric and spectroscopic observations, and the analysis techniques that have been developed in recent years to account for activity-induced RV signals. I also present the target selection cr

I will start from the very basics of Gaussian distributions, leading up to how I incorporate them in my model to account for stellar activity signals. I then present the model that I use to fit RV observat

Building on my thesis work, I now intend to tackle this issue in two ways. First, I plan to incorporate activity proxies into
