A Analysis of the Light and Radial Velocity Curves of do CAS [PDF]
Journal of Astronomy and Space Sciences, 2000 DO Cas is a short period (P=0.68day) eclipsing binary star and is classified as a near-contact binary by Shaw (1990). There is no published radial velocity curve for this short period binary after Mannino (1958).

Extreme Long Period Eclipsing Binary Epsilon Aurigae [PDF]
Journal of Astronomy and Space Sciences, 1990 From the study of a spectroscopic plate of epsilon Aurigae, we can measure the radial velocity and the relative abundance for this eclipsing binary. Calculated radial velocity is -37 Km/s and the abundance of [Fe] is estimated as -1.5.

Velocity Dispersion of the Open Cluster NGC 2571 by Radial Velocities and Proper Motions
The Astronomical JournalWe use a kernel density estimator method to evaluate the stellar velocity dispersion in the open cluster NGC 2571. We derive the 3D velocity dispersion using both proper motions as extracted from Gaia Data Release 3 and single-epoch radial velocities as ...

Radial Velocities as an Exoplanet Discovery Method [PDF]
, 2017 The precise radial velocity technique is a cornerstone of exoplanetary astronomy. Astronomers measure Doppler shifts in the star's spectral features, which track the line-of/sight gravitational accelerations of a star caused by the planets orbiting it.
