  We report on the detection of four extrasolar planets orbiting evolved
intermediate-mass stars from a precise Doppler survey of G and K giants at
Okayama Astrophysical Observatory. All of the host stars are considered to be
formerly early F-type or A-type dwarfs when they were on the main sequence. 14
And (K0 III) is a clump giant with a mass of 2.2 M_solar and has a planet of
minimum mass m_2sin i=4.8 M_Jup in a nearly circular orbit with a 186 day
period. This is one of the innermost planets around evolved intermediate-mass
stars and such planets have only been discovered in clump giants. 81 Cet (G5
III) is a clump giant with 2.4 M_solar hosting a planet of m_2sin i=5.3 M_Jup
in a 953 day orbit with an eccentricity of e=0.21. 6 Lyn (K0 IV) is a less
evolved subgiant with 1.7 M_solar and has a planet of m_2sin i=2.4 M_Jup in a
899 day orbit with e=0.13. HD 167042 (K1 IV) is also a less evolved star with
1.5 M_solar hosting a planet of m_2sin i=1.6 M_Jup in a 418 day orbit with
e=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, which
supports the lack of metal-rich tendency in planet-harboring giants in contrast
to the case of dwarfs.
