RECONS Mission Statement
The purpose of RECONS is to understand the nature of the Sun's
nearest stellar neighbors, both individually and as a population. Our
primary goals are to discover ``missing'' members of the stellar
sample within 10 parsecs (32.6 light years), and to characterize all
stars and their environments within that distance limit. New members
are found via astrometric, photometric, and spectroscopic techniques,
and through searches for stellar, brown dwarf, and planetary
companions at small and large separations. Characterization includes
photometry and spectroscopy at both optical and infrared wavelengths,
as well as determinations of the luminosity function, mass function,
and multiplicity fraction of the nearby stars. RECONS is currently
extending survey work to 25 parsecs in an effort to understand the
Sun's and Earth's places among a larger population of our neighbors.
We request that if you use data from this website,
please acknowledge RECONS.
Current support for RECONS comes from the
National Science Foundation under grant AST-0908402. Our primary
observing programs are carried out via the SMARTS Consortium, which
operates four telescopes in the Chilean Andes under the auspices of
National Optical Astronomy Observatory and the National Science
Foundation.

about the logo
The RECONS logo image is an infrared picture of
the Alpha Centauri system taken while observing at the Cerro Tololo
Inter-american Observatory near La Serena, Chile. The mirror cover at
the 1.5m telescope, which has segments much like flower petals, was
partially closed, causing the diffraction effects seen for each of the
two stars, Alpha Centauri A and B. These two stars and Proxima
Centauri (beyond the field of view) comprise the nearest stellar
system to the Sun, which is, in fact, a triple star system.
