A possible means of describing that involves the velocities induced by the eddies, and the most useful velocity for this purpose is the radial velocity. From the Cambridge English Corpus Specific topics to be addressed include, (1) an overview of the current state of the radial velocity and transit searches for planets.
Exoplanet radial velocity curve. Here the orbit of an unseen exoplanet and parent star is shown on the left (masses exaggerated) and the radial velocity of Radial velocity Stars with planets aren't stationary. We often picture our Solar System with the Sun in the middle, completely stationary, while all the planets move around it. However, this isn’t true – in reality, the planets and the Sun orbit their common centre of mass.

A gyroscopic effect induced by the swirl leaving the It can display the latest reflectivity, velocity, dual-polarization, and other data rendered in its original radial format for a high level of detail.
Doppler spectroscopy (also known as the radial-velocity method, or colloquially, the wobble method) is an indirect method for finding extrasolar planets and brown dwarfs from radial-velocity measurements via observation of Doppler shifts in the spectrum of the planet's parent star.

The radial velocity is usually measured using the observed Doppler shift of spectral lines, given by the formula Δλ/λ = v/c, where Δλ is the shift in wavelength observed for the object compared to the rest wavelength, λ; v is the velocity of the object along the line of sight; and c is the speed of light, 299,792 km/s.
Radial velocity profiles show good agreement with data, the main discrepancies being the underestimation of the extent of the downward flow at z/H = 0.9. The radial velocity of our Sun measured from a point coplanar to the plane of the solar system. The strong signal with a period of 12 years and a semiamplitude of 12.5 m s −1 is caused by Jupiter, while the longer periodic and smaller variation is the signal caused by Saturn. The radial velocity variations due to the other planets are negligible.
