Scientific paper

Doppler monitoring of a sample of 1330 stars with a precision of 3 m s-1 is discussed. Seventy five planets residing in 65 systems have been discovered within this sample, a detection rate of 5%. Eight multiple systems are found in the sample, and roughly half of the systems with one known planet appear to harbor additional companion(s). The incidence of ``hot jupiters'', orbiting within 0.1 AU is 1.0 %. There appears to be a ``pile up'' of planets at P=3 days. Planets with even shorter periods could easily be detected but none was found indicating they are exceedingly rare.
