Abstract
The problem of planets around solar type stars is reinvestigated using model stellar atmospheres and synthetic spectra. It is shown that a p ossible stellar companion may be spectroscopically well hidden. The ch anges in the corresponding line profile shapes are too small to be see n. Consequently, an erroneous classification of such secondary as a pl anet is possible.
