Exploring the robustness of Keplerian signals to the removal of active and telluric features
(2020-10-22)
We examine the influence of activity- and telluric-induced radial velocity signals on high resolution spectra taken with an iodine absorption cell. We exclude 2 Angstrom spectral chunks containing active and telluric lines ...
The impact of unresolved magnetic spots on high precision radial velocity measurements
(2020-07-23)
The Doppler method of exoplanet detection has been extremely successful, but suffers from contaminating noise from stellar activity. In this work a model of a rotating star with a magnetic field based on the geometry of ...
