Examples

By 1887, the photographic technique had improved to the point that it was possible to measure a star's radial velocity from the amount of Doppler shift in the spectrum. Source: Internet

By analysing its radial velocity from its spectrum, Pugh and colleagues calculated a period of 5.93 ± 0.01 years and considered whether this change was orbital or pulsational. Source: Internet

Both discovered in 2011 by the radial velocity method, the two tiny planets orbit very close to their host star. Source: Internet

Further variability in the radial velocity of Barnard's Star was attributed to its stellar activity. Source: Internet

HD 210277 b was discovered earlier than most of the other planets in Aquarius, detected by the radial velocity method in 1998. Source: Internet

In 2003, Barnard's Star presented the first detectable change in the radial velocity of a star caused by its motion. Source: Internet
