Radial velocity follow-up of GJ1132 with HARPS [PDF]
Astronomy & Astrophysics, 2018 The source GJ1132 is a nearby red dwarf known to host a transiting Earth-size planet. After its initial detection, we pursued an intense follow-up with the HARPS velocimeter. We now confirm the detection of GJ1132b with radial velocities alone.

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.

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 ...

COMMISSION 30: RADIAL VELOCITIES [PDF]
Proceedings of the International Astronomical Union, 2008 The past three-year period has seen steady efforts to collect large numbers of radial-velocity (RV) measurements, as well as important applications of radial velocities to astrophysics. Improvements in precision continue to be driven largely by exoplanet research.

The Open Cluster NGC 7789: I. Radial Velocities for Giant Stars
, 1998 A total of 597 radial-velocity observations for 112 stars in the ~1.6 Gyr old open cluster NGC 7789 have been obtained since 1979 with the radial velocity spectrometer at the Dominion Astrophysical Observatory. The mean cluster radial velocity is -54.9 +/

Propagation velocities of gas rings in collisional ring galaxies [PDF]
, 2003 The propagation velocity of the first gas ring in collisional ring galaxies, i.e. the velocity at which the maximum in the radial gas density profile propagates radially in the galactic disk, is usually inferred from the radial expansion velocity of gas ...

The Joker: A Custom Monte Carlo Sampler for Binary-star and Exoplanet Radial Velocity Data [PDF]
, 2016 Given sparse or low-quality radial velocity measurements of a star, there are often many qualitatively different stellar or exoplanet companion orbit models that are consistent with the data.
