Reconstructing the solar integrated radial velocity using MDI/SOHO
, 2010 Searches for exoplanets with radial velocity techniques are increasingly sensitive to stellar activity. It is therefore crucial to characterize how this activity influences radial velocity measurements in their study of the detectability of planets in ...

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.

Velocity and velocity bounds in static spherically symmetric metrics
, 2010 We find simple expressions for velocity of massless particles in dependence of the distance $r$ in Schwarzschild coordinates. For massive particles these expressions put an upper bound for the velocity.

Starspot-induced optical and infrared radial velocity variability in T Tauri star Hubble 4 [PDF]
, 2011 We report optical (6150 Ang) and K-band (2.3 micron) radial velocities obtained over two years for the pre-main sequence weak-lined T Tauri star Hubble I 4.

Radial velocity moments of dark matter haloes
, 2005 Using cosmological N-body simulations we study the radial velocity distribution in dark matter haloes focusing on the lowest-order even moments, dispersion and kurtosis.
