Query: New distant companions to known nearby stars: I. GJ 4047B, GJ 718B, GJ
  747.2C, GJ 4100B, and GJ 4153B   In an ongoing survey for high proper motion stars at low galactic latitudes,
we have identified 5 previously uncatalogued common proper motion companions to
stars listed in the Preliminary Version of the Third Catalogue of Nearby Stars
(GJ stars). For each system, the relative proper motion between the components
is less than 5% of the common proper motion of the pair. Spectra of the pairs
have been obtained at the Lick 3-m Shane Telescope, confirming that the systems
are indeed wide separation binaries. The systems are classified as follows: GJ
4047AB = K5 V + M5 V, GJ 718AB = K5 V + M4.5 V, GJ 747.2ABC = (K7 V + K7 V) +
M4 Ve, GJ 4100AB = M1 V + M4.5 Ve, and GJ 4153AB = M0.5 V + M3.5 V. The total
area surveyed contains 346 Gliese stars, which suggests that approximately 1.5%
of the stars listed in the Preliminary Version of the Third Catalogue of Nearby
Stars have unrecognized proper motion companions. We predict that 15-50 more
new distant companions to GJ stars will be discovered in the Digitized Sky
Survey.
