The effect of stellar activity on the detection of terrestrial planets - Livestream

Stars undergo activity cycles often lasting many years. During these periods surface phenomena on their surfaces may not only make exoplanet planet detection and characterisation difficult but, in some cases, may produce spurious signals that mimic those expected from exoplanet mass companions. Here we look at the menagerie of processes occurring and look at ways to minimize their effects. Further developments will be needed if we are to reach sufficient accuracy to detect earth analogue systems or to reveal atmospheres of small planets.
