The nature of lowlatitude stellar structure is controversial: Galactic feature or satellite accretion? Low inclination, circular satellite orbits are very unlikely in theoretical models based on the CDM theory. Is the Monoceros ring the signature of the Galactic flare or the outer region of the MW warped
A comprehensive model of the Monoceros Stream An extraordinary observational effort in the last year for different groups to trace this stream. Best orbit obtained using semianalitical model from fitting to position, distance and velocities of stream stars (151200 simulations) Nbody simulation for the best orbit, including dynamical friction included Observational data consistents with a huge tidal stream disrupted in the last 2.5 Gyr
