Abstract
Among 120 extrasolar planets discovered to date, only 20 planets exist in multiple star systems.Recent theoretical study predicts that a planet can be stable in a multiplestar system which has a large semimajor axis, but current searches for planetsin multiple star systems are less extensive than those around in single stars.We have started a search for extrasolar planets in binary systems by preciseDoppler shift measurements from 2003,using HIgh Dispersion Echelle Spectrograph(HIDES) at the Okayama Astrophysical Observatory.We here report the current status of the survey.
