Abstract (from CDS):

We search for signatures of planets in 43 intensively monitored microlensing events that were observed between 1995 and 1999. Planets would be expected to cause a short-duration (∼1 day) deviation on the smooth, symmetric light curve produced by a single lens. We find no such anomalies and infer that less than one-third of the ∼0.3 M_☉ stars that typically comprise the lens population have Jupiter mass companions with semimajor axes in the range of 1.5 AU<a<4 AU. Since orbital periods of planets at these radii are 3-15 yr, the outer portion of this region is currently difficult to probe with any other technique.
