Decoding the Radial Velocity Signatures of Solar Faculae with 3D MHD Simulations
Florian Kröll, Sowmya Krishnamurthy, Alexander Shapiro +8
We model the solar radial velocity (RV) signal induced by faculae, the dominant contributor to RV variability in Sun-like stars. We use a representative case of a facular patch tra…

Mitigating stellar radial velocity jitter using orthogonal activity indices and a time-aware neural network
Jordi Blanco-Pozo, Manuel Perger, Guillem Anglada-Escudé +7
Despite recent advances in the precision of high-resolution spectrographs, the detection of Earth-like exoplanets is still limited by the effects of stellar activity, which introdu…
