Query: Search for Close Stellar Encounters with the Solar System from Data on
  Nearby Dwarfs   Trigonometric parallaxes measured with ground-based telescopes of the RECONS
consortium as part of the CTIOPI program are used to search for stars that have
either had an encounter with the solar system in the past or will have such an
encounter in the future, at distances of less than a few parsecs. These are
mainly low-mass dwarfs and subdwarfs of types M, L, and T currently at
distances of less than 30 pc from the Sun. Six stars for which encounters with
the solar orbit at distances of less than 1 pc are possible have been
identified for the first time. For example, the minimum distance for the star
**SOZ 3A will 0.72+/- 0.11 pc at an epoch of 103+/-44 thousand years in the
future.
