Long-term radial-velocity variations of the Sun as a star: The HARPS view [PDF]
Stellar radial velocities play a fundamental role in the discovery of extrasolar planets and the measurement of their physical parameters as well as in the study of stellar physical properties.

Radial velocities of giant stars: an investigation of line profile variations [PDF]
Since 1999, a radial velocity survey of 179 red giant stars is ongoing at Lick Observatory with a one month cadence. At present ~20-100 measurements have been collected per star with an accuracy of 5 to 8 m/s.

VARIATIONS OF THE β CEPHEI Hα LINE PARAMETERS IN 1993 - 1998.
We use high-dispersion CCD spectrograms obtained in 1993 - 1998 to study parameter variations of the absorption and emission components Hα line of the star β Cephei. We show that radial velocity of the emission component does not depend on star pulsation

Radial velocity moments of dark matter haloes
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.

Starspot-induced optical and infrared radial velocity variability in T Tauri star Hubble 4 [PDF]
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.
