Scientific paper

Grillmar and Dionatos (2006) announced the detection of a 63 degree cold stellar stream in the Sloan Digital Sky Survey (SDSS). We use radial velocity measurements from SDSS and Sloan Extension for Galactic Understanding and Evolution (SEGUE) data to constrain the orbit of the stream, and match this with semi-analytic N-body simulations of globular cluster disruptions in the Milky Way potential to constrain the parameters for the progenitor. This project was funded by the National Science Foundation, AST 06-07618.
