The 20 pages that link to Radial velocity, each with the reason it gives.

• Doppler effectRelated: A frequency shift measures motion along the line of sight, not transverse motion alone.

• Binary starRelated: Alternating Doppler shifts reveal each star's motion toward and away from Earth.

• Stellar spectroscopyRelated: Stellar line shifts measure approach or recession relative to an observer.

• Proper motionRelated: Together with proper motion and distance, radial velocity specifies a star's three-dimensional motion.

• Variable starRelated: Velocity measurements can confirm orbital motion behind eclipsing or binary variability.

• Fraunhofer linesRelated: Shifts in stellar absorption lines measure motion toward or away from Earth.

• Mount Wilson ObservatoryRelated: Astronomers used spectral shifts to measure how stars and galaxies moved toward or away from Earth.

• RadiusRelated: It describes motion along a radial direction measured from a chosen center.

• Stellar kinematicsRelated: It supplies the line-of-sight component missing from proper motion.

• Vesto SlipherRelated: His spectra yielded estimates of nebulae’s motion along the line of sight.

• GaiaRelated: Gaia’s spectrometer adds line-of-sight velocities to stars’ transverse motions.

• Jan OortRelated: Combined with proper motions, it helped map nearby stellar movement.

• RigelRelated: Rigel’s changing radial velocity provides evidence of orbital motion in its system.

• Barnard's StarRelated: Combined with proper motion, it describes Barnard's Star's motion through space.

• Galactic astronomyRelated: It supplies the line-of-sight component needed to reconstruct stellar motions.

• Messier 15Related: Spectroscopic velocities reveal the cluster's motion and help measure its internal dynamics.

• Beehive ClusterRelated: Radial velocities provide another way to distinguish cluster members from foreground stars.

• Beta CentauriRelated: Periodic radial-velocity shifts reveal orbital motion among the system’s stars.

• Pi PuppisRelated: Spectral shifts can reveal orbital motion not apparent from sky positions alone.
