摘要：

The problem of planets around solar type stars is reinvestigated using model stellar atmospheres and synthetic spectra. It is shown that a possible stellar companion may be spectroscopically well hidden. The changes in the corresponding line profile shapes are too small to be seen. Consequently, an erroneous classification of such secondary as a planet is possible.
