摘要：
A high-resolution N-body simulation suggests that stellar streams in the discs of barred galaxies are common and strongly time-dependent. The velocity distribution of stars in the Solar neighbourhood betray many such streams, including a stream of outward moving stars with low angular momentum. This stream is interpreted as a signature of the Galactic bar, in the sense that its stars have just enough energy (Jacobi's integral) to cross the corotation resonance.
