[1] The team used data from the UVES spectrograph on ESO's Very Large Telescope in Chile (to determine the properties of the star accurately), the Carnegie Planet Finder Spectrograph (PFS) at the 6.5 - metre Magellan II Telescope at the Las Campanas Observatory in Chile, the HIRES spectrograph mounted on the Keck 10 - metre telescope on Mauna Kea, Hawaii as well as extensive previous data from HARPS (the High Accuracy Radial velocity Planet Searcher) at ESO's 3.6 - metre telescope in Chile (gathered through the M dwarf programme led by X. Bonfils and M. Mayor 2003 - 2010.

The other is the regular but minuscule variation in a star's radial velocity — its speed through the galaxy relative to Earth's speed — which indicates that the star is being tugged by an orbiting planet's gravity.

We identified the initial transit signal in the KELT - North survey data and established the planetary nature of the companion through precise follow - up photometry, high - resolution spectroscopy, precise radial velocity measurements, and high - resolution adaptive optics imaging.

Based on radial - velocity observations through 2009, no substellar companions were detected around Gl 433's habitable zone down to within a few Earth - masses (Zechmeister et al, 2009).

A spectrograph spreads out the light gathered by a telescope so that it can be analysed to determine properties of celestial objects such as chemical composition or their radial velocity through the Doppler effect.

The 1995 discovery of 51 Peg b, through Doppler velocity techniques, ushered in a new era of radial velocity discovery.
