Thin disk kinematics from RAVE and the solar motion [PDF]
, 2012 Aims. We study the Milky Way thin disk with the Radial Velocity Experiment (RAVE) survey. We consider the thin and thick disks as different Galactic components and present a technique to statistically disentangle the two populations.

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 ...

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)

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.

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

Precise radial velocities of giant stars VIII. Testing for the presence of planets with CRIRES Infrared Radial Velocities [PDF]
, 2015 We have been monitoring 373 very bright (V < 6 mag) G and K giants with high precision optical Doppler spectroscopy for more than a decade at Lick Observatory.

Commission 30: Radial Velocities: (Vitesses Radiales) [PDF]
Transactions of the International Astronomical Union, 2000 Commission 30 has 120 members in 28 countries who are active in the area of radial velocities. During the past triennium 11 new members have joined the commission. The work of the commission covers a wide range of topics all of which concern the application of the Doppler effect to astronomical objects, including galaxies and the interstellar medium as

The LCES HIRES/Keck Precision Radial Velocity Exoplanet Survey [PDF]
, 2017 We describe a 20 year survey carried out by the Lick-Carnegie Exoplanet Survey Team (LCES), using precision radial velocities from HIRES on the Keck I telescope to find and characterize extrasolar planetary systems orbiting nearby F, G, K, and M dwarf ...
