英文摘要
One of the driving forces in exoplanet research is the detection of smaller exoplanets using the radial velocity technique. To achieve this many new instruments will be built or have recently started operations. With the high precision that can be obtained with these instruments, stellar convective processes or stellar jitter that vary on levels of m/s, which is the precision required to detect an Earth-like planet, start to become significant. In this proposal we will make a significant step in understanding how stellar jitter impacts the detection of small exoplanets and how best to identify and mitigate its effect. The results of this work will maximise the scientific results from current and future exoplanet radial velocity surveys.
