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…

Identifying activity induced RV periodicities and correlations using Central Line Moments
J. R. Barnes, S. V. Jeffers, C. A. Haswell +5
The radial velocity (RV) method of exoplanet detection requires mitigation of nuisance signals arising from stellar activity. Using analytic cool and facular spot models, we explor…
