Scientific paper

Grillmair and Dionatos (2006) announced the detection of a 63 degree cold stellar stream in the Sloan Digital Sky Survey (SDSS). We use newly acquired radial velocity and distance measurements from SDSS DR 7 and Sloan Extension for Galactic Understanding and Evolution (SEGUE) data to constrain the orbit of the progenitor within a variety of Milky Way potential models. This project was funded by the National Science Foundation, AST 06-07618.
