ℓ1 periodogram for the stars HD 10700 (left), HD 102365 (centre), and HD 304636 (right). The ten strongest peaks periods are identified in the image; the associated FAP is listed in Table F. -- astro-ph.EP

A Comprehensive Study On Radial Velocity Signals Using ESPRESSO: Pushing Precision To The 10 cm/s Level

by Keith CowingJuly 11, 2025

We analyse ESPRESSO data for the stars HD10700, HD20794, HD102365, and HD304636 acquired via its Guaranteed Time Observations (GTO) programme. We characterise the stars’ radial velocity (RV) signals down to […]

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.
