Detection of a Tidal Tail Associated with the Globular Cluster M 13
Abstract
Using Sloan Digital Sky Survey data, we detect tidal tails that appear to emanate from the globular cluster M 13 (NGC 6205). Both leading and trailing tails are detected, extending for at least 15 degrees on the sky. The tails agree approximately with the orbit of the cluster, as determined from radial velocity and proper motion measurements. On the other hand, initial estimates of the distance to the stream put it at least 5 kpc beyond M 13. We discuss some possible consequences of this finding.
