The '''Okayama Planet Search Program''' (OPSP) was started in 2001 with the goal of spectroscopically searching for planetary systems around stars. It reported on the detection of 3 new [[extrasolar planets]]: ([[18 Delphini b]], [[Xi Aquilae b|xi Aql b]], and [[41 Lyncis b]]), around intermediate-mass G and [[K star|K giants]] [[18 Delphini]], [[Xi Aquilae]], and [[HD 81688]]. Also, it updated the orbital parameters of [[HD 104985 b]], the first planet discovered around the [[G star|G giants]] from the survey, by using the data collected during the past six years. Since 2001, it has been conducting a precise [[Doppler effect|Doppler]] [[Astronomical survey|survey]] of about 300 G and K giants using a 1.88m telescope, the High Dispersion Echelle Spectrograph ([[HIDES]]), and an iodine absorption cell [[I2 cell]] at the [[Okayama Astrophysical Observatory]] (OAO). |

The Okayama Planet Search Program (OPSP) was started in 2001 with the goal of spectroscopically searching for planetary systems around stars. It reported on the detection of 3 new extrasolar planets: (18 Delphini b, xi Aql b, and 41 Lyncis b), around intermediate-mass G and K giants 18 Delphini, Xi Aquilae, and HD 81688. Also, it updated the orbital parameters of HD 104985 b, the first planet discovered around the G giants from the survey, by using the data collected during the past six years. Since 2001, it has been conducting a precise Doppler survey of about 300 G and K giants using a 1.88m telescope, the High Dispersion Echelle Spectrograph (HIDES), and an iodine absorption cell I2 cell at the Okayama Astrophysical Observatory (OAO).
