Scientific paper

The searching for `other worlds' is one of the oldest well known scientific questions. With the first discovery of planets around the pulsar PSR1257+12 (Wolszczan & Frail 1992) and the main sequence star 51 Peg (Mayor & Queloz 1995), a new field of astronomy has been opened. Most of the planets have been found around main-sequence solar-mass stars. However in this investigation, we present our plan to search for planets around intermediate-mass late G type giant stars (1.5 - 3Msolar) with cooperation with Japanese astronomers and give the preliminary results of this research. A long-term monitoring of the Doppler velocities of stars will be carried out with mid-size telescopes at Okayama (Japan) and Xinglong (China).
