The Topin system was a star system in the Alpha Quadrant. It was a binary star system which had an unstable protostar that generated an enormous amount of magnetascopic interference rendering most sensors and communications unreliable. This system was near the Demilitarized Zone between the Cardassian Union and the United Federation of Planets.
In 2370, the USS Enterprise-D responded to a distress call from a Federation science vessel originating in the Topin system. The distress call was in fact a ploy by Ro Laren to lure the Enterprise to the system for the purpose of stealing medical supplies which she transferred to the Maquis. (TNG: "Preemptive Strike")
According to Star Trek: Star Charts (p. 46) and Stellar Cartography: The Starfleet Reference Library ("Federation Historical Highlights, 2161-2385"), the stars of this system were a G-class star and a K-class star. In the late 24th century, it was an independent system.
