TOP: Same as Fig 6 but for the HARPS-N solar spectral time series with the HD10700 sampling. BOTTOM: Exoplanet detection limits on HD128621 HARPS spectra. We derived the detection limit maps by injecting simulated planetary signals covering periods ranging from 10 to 300 days and semiamplitude ranging from 0.4 to 1.1 m/s, into the spectra. Left: Detection limit map in the period-amplitude domain. The red dots indicate the successful detection by the trained neural network of a signal with a FAP > 0.1%. Middle: Amplitude comparison between the injected and recovered signals in the period amplitude domain. The amplitude difference for most of the detected signals is < 30%. Right: Phase difference between the injected and recovered signals in the period-amplitude domain. The phase difference for most of the detected signals is < 0.06. -- astro-ph.EP

Improving Earth-like Planet Detection in Radial Velocity Using Deep Learning

by Keith CowingMay 24, 2024May 24, 2024

Many novel methods have been proposed to mitigate stellar activity for exoplanet detection as the presence of stellar activity in radial velocity (RV) measurements is the current major limitation.
