In the four years following the discovery of a planet orbiting the star 51 Pegasi, about 20 other planets have been detected through their influence on the radial velocities of lines in the stellar spectra. The orbital motion of the planet is detected through the smaller ‘reflex motion’ of the star, which can be measured using high-precision spectroscopy. This indirect technique cannot investigate the radius or composition of the planet, and can place only a lower limit on its mass. Here we… CONTINUE READING
