3 , ▁a ▁planet ▁was ▁announced ▁orbit ing ▁the ▁giant ▁star . ▁ ▁A ▁do pp ler ▁spect rom eter ▁was ▁used ▁to ▁look ▁for ▁effects ▁on ▁the ▁star ▁caused ▁by ▁the ▁gravit ational ▁t ug ▁of ▁the ▁orbit ing ▁planet . ▁Using ▁the ▁amplitude ▁from ▁the ▁radial ▁velocity ▁method , ▁he ▁calculated ▁the ▁planet ary ▁mass ▁as ▁ 5 . 2 5 ▁Jup iter ▁masses ▁and ▁with ▁period ▁ 3 0 3 ▁days . ▁However ▁that ▁mass ▁is ▁only ▁a ▁minimum ▁because ▁the ▁incl ination ▁of ▁the ▁orbit ▁is ▁not ▁known . ▁Using ▁the ▁stell ar ▁mass ▁and ▁period , ▁he ▁calculated ▁the ▁sem im aj or ▁axis ▁as ▁ 0 . 9 1 1 ▁astronom ical ▁units . ▁He ▁found ▁that ▁the ▁shape ▁of ▁the ▁stell ar ▁wob ble ▁is ▁circular , ▁imp lying ▁that ▁the ▁planet ▁has ▁zero ▁ecc ent ric ity . ▁ ▁References ▁ ▁External ▁links ▁▁▁▁ ▁Category : K - type ▁gi ants ▁Category : Plan et ary ▁systems ▁with ▁one ▁confirmed ▁planet ▁Category : S pect ro scop ic ▁bin aries ▁ ▁Category : G em ini ▁( const ell ation ) ▁Category : D urch m uster ung ▁objects ▁ 0 5 9 6 8 6 ▁ 0 3 6 6 1 6 ▁ 2 8 7 7 <0x0A> </s> ▁Con us ▁g amb i ensis ▁is ▁a ▁species ▁of ▁sea ▁sn ail , ▁a ▁marine ▁g ast rop od ▁m oll usk , ▁in ▁the ▁family ▁Con idae , ▁the ▁cone ▁sn ails ▁and
