Radial-Velocity Standards

International Astronomical Union Colloquium, 1984
AbstractThe writer reviews the presently available lists of standard-velocity stars approved by IAU Commission 30 and suggests that the time has arrived for major revisions. Many of the currently adopted standards are known or suspected to be variable in velocity at the level of precision to which we can now work. The writer suggests that we need three

Radial velocities of isolated galaxies

Astrophysics, 1979
For 16 galaxies in our list there are independent estimates of the radial velocities based on observations with different telescopes [2-4]. In ten cases out of the 16, the values of V 0 agree to within the errors of the measurements. The mean difference of the estimates is = --14 • 22 (km/sec). The rms difference of the estimates, < ~V~ m_oth } _/2 =

The Radial Velocities of the Stars

1928
The determination of radial velocities of all stars brighter than magnitude 6,0 nears completion and a large number of velocities of stars down to magnitude 8,5 are also determined. For still fainter stars the present methods of velocity determination are too time-consuming to make possible any rapid progress for these stars. The use of objective prism

Precision radial velocities

Publications of the Astronomical Society of the Pacific, 1983
A number of techniques for determining stellar radial velocities with a precision better than 100 m s-1 are now becoming available. Three types of precision velocity techniques have been proposed, using for wavelength reference either telluric lines, Fabry-Perot fringes, or lines generated in an absorption cell. The author has used the latter technique,
