article_snippet.sent: Repeated measurement of a star's spectrum enables astronomers to detect the tiny wobble induced in a star by the gravitational tug of an orbiting planet.
article_snippet.sent: AFP found the star system by tracing out The three planets orbits over many years using the Doppler technique to see shifts in their host star's light.
article_snippet.sent: the star system was also spotted by the Keck Observatory and the Automatic Photometric Telescope (APT) at Fairborn Observatory in Arizona.

article_snippet.sent: This discovery shows the type of planetary system that astronomers expect to find around many nearby stars in the coming years. '
article_snippet.sent: Starspots, like sunspots on the sun, can momentarily mimic the signatures of small planets. '
article_snippet.sent: Repeated observations over many years allowed us to separate the starspot signals from the signatures of these new planets,' explains Evan Sinukoff, a UH graduate student who contributed to This discovery.
