CTIOPI: Cerro Tololo Interamerican Observatory Parallax Investigation

The purpose of CTIOPI is to discover nearby red, white, and brown dwarfs that lurk unidentified in the solar neighborhood. Our goal is to discover 300 new southern star systems within 25 parsecs by determining trigonometric parallaxes accurate to 3 milliarcseconds. In addition, under the aegis of ASPENS (Astrometric Search for Planets Encircling Nearby Stars), we will concentrate efforts on ~100 nearby red and white dwarfs to detect very low mass companions. CTIOPI is a project carried out by a team of astronomers from the United States and Chile using the 0.9m and 1.5m CTIO telescopes located in the Chilean Andes. CTIOPI began under the auspices of the NOAO Surveys Program in 1999, and continues via the SMARTS Consortium.
