Abstract:
We perform a search for faint, common proper motion companions of
Hipparcos stars using the recently published Lepine-Shara
Prope-Motion-North catalog of stars with proper motion µ>0.15"/yr.
Our survey uncovers a total of 521 systems with angular separations
3"<Δθ<1500", with 15 triples and 1 quadruple. Our new list
of wide systems with Hipparcos primaries includes 130 systems
identified here for the first time, including 44 in which the
secondary star has V>15.0. Our census is statistically complete for
secondaries with angular separations 20"<Δθ<300" and
apparent magnitudes V<19.0. Overall, we find that at least 9.5% of
nearby (d<100pc) Hipparcos stars have distant stellar companions with
projected orbital separations s>1000AU.
