We report on the detection of four extrasolar planets orbiting evolvedintermediate-mass stars from a precise Doppler survey of G and K giants atOkayama Astrophysical Observatory. All of the host stars are considered to beformerly early F-type or A-type dwarfs when they were on the main sequence. 14And (K0 III) is a clump giant with a mass of 2.2 M_solar and has a planet ofminimum mass m_2sin i=4.8 M_Jup in a nearly circular orbit with a 186 dayperiod. This is one of the innermost planets around evolved intermediate-massstars and such planets have only been discovered in clump giants. 81 Cet (G5III) is a clump giant with 2.4 M_solar hosting a planet of m_2sin i=5.3 M_Jupin a 953 day orbit with an eccentricity of e=0.21. 6 Lyn (K0 IV) is a lessevolved subgiant with 1.7 M_solar and has a planet of m_2sin i=2.4 M_Jup in a899 day orbit with e=0.13. HD 167042 (K1 IV) is also a less evolved star with1.5 M_solar hosting a planet of m_2sin i=1.6 M_Jup in a 418 day orbit withe=0.10. This planet was independently announced by Johnson et al. (2008, ApJ,675, 784). All of the host stars have solar or sub-solar metallicity, whichsupports the lack of metal-rich tendency in planet-harboring giants in contrastto the case of dwarfs.
