Up to day information on exoplanets or extrasolar planets gives about 60 main-sequence and subgiants stars with such planets turning around them (Schneider 2001). But many observed candidate late-type stars had not shown just now any sign of the presence of any exoplanet around them. With the information collected until now, could it be possible to establish some criteria, based on relevant known stellar characteristics, to distinguish stars with and without exoplanets? High resolution spectra probably are going to differentiate the two categories of stars, but some doubts still persist about for example, the claims that stellar supermetallicity is the best criterium giving higher probability to find extrasolar planetary systems. We review recent bibliography and we will try to counterbalance arguments.
