radial velocity curve

What with such a short period, I had the radial velocity curves for each star almost as soon as the discovery was made.

In addition to CoRoT photometry, a spectroscopic follow-up was performed which yielded the radial velocity curves, the component effective temperatures, the metallicity, and the line-of-sight projected rotational velocities.

Based on residuals in the radial velocity curve, a planet in an eccentric orbit with a period of approximately 600 days was proposed, but this was not confirmed and it seems likely that the effect was due to activity on Iota Horologii itself.

Van de Kamp never admitted that his claim was in error and continued to publish papers about a planetary system around Barnard's Star into the 1980s, while modern radial velocity curves place a limit on the planets much smaller than claimed by Van de Kamp.

One of the main advantages of the beaming effect is the possibility to determine the radial velocity directly from the light curve but very different luminosities of the binary components are required and a single radial velocity curve can only be obtained as in an SB1 binary system.
