Quantifying the Bayesian Evidence for a Planet in Radial Velocity Data [PDF]
Astronomical Journal, 2018 We present results from a data challenge posed to the radial velocity (RV) community: namely, to quantify the Bayesian “evidence” for n = {0, 1, 2, 3} planets in a set of synthetically generated RV data sets containing a range of planet signals ...

Radial velocity observations of VB10
EPJ Web of Conferences, 2011 VB 10 is the smallest star known to harbor a planet according to the recent astrometric study of Pravdo & Shaklan [1]. Here we present near-infrared (J-band) radial velocity of VB 10 performed from high resolution (R~20,000) spectroscopy (NIRSPEC/KECK II)

pyaneti: a fast and powerful software suite for multiplanet radial velocity and transit fitting [PDF]
Monthly notices of the Royal Astronomical Society, 2018 Transiting exoplanet parameter estimation from time-series photometry and Doppler spectroscopy is fundamental to study planets' internal structures and compositions. Here we present the code pyaneti, a powerful and user-friendly software suite to perform

AESTRA: Deep Learning for Precise Radial Velocity Estimation in the Presence of Stellar Activity
The Astronomical Journal, 2023 Stellar activity interferes with precise radial velocity measurements and limits our ability to detect and characterize planets, in particular Earth-like planets.

Spectrum radial velocity analyser (SERVAL). High-precision radial velocities and two alternative spectral indicators [PDF]
, 2017 Context: The CARMENES survey is a high-precision radial velocity (RV) programme that aims to detect Earth-like planets orbiting low-mass stars. Aims: We develop least-squares fitting algorithms to derive the RVs and additional spectral diagnostics ...
