Abstract:
|
Recent years have seen a proliferation in the number of exoplanets (planets orbiting stars outside our Solar System) discovered. One technique for uncovering exoplanets relies on the detection of subtle shifts in the stellar spectra due to the Doppler effect caused by an orbiting object. However, features on the surface of a star such as spots and plages cause distortions in the spectra that mimic the imprint of an orbiting exoplanet. I will discuss some statistical issues related to separating the stellar "noise" from a planetary signal.
