Radial Velocity Observations of Binary Stars
Published online by Cambridge University Press: 12 April 2016
Abstract
This review considers three main areas, leaving several others to be discussed in more detail in the contributed papers of this session.
1. The need for spectrographs and measuring instruments of great stability for long-term projects such as radial velocity observations of visual binary stars.
2. The use of cross-correlation devices, both analog (radial velocity scanners) and digital, for radial velocity measurement.
3. The use of comparison spectra impressed directly onto the starlight and of polarisation instruments as means to very precise radial velocities.
