Generation of mock tidal streams

Understand

In this paper we discuss a method for the generation of mock tidal streams.

• Using an ensemble of simulations in an isochrone potential where the actions and frequencies are known, we derive an empirical recipe for the evolving satellite mass and the corresponding mass loss rate, and the ejection conditions of the stream material.
• The resulting stream can then be quickly generated either with direct orbital integration, or by using the action-angle formalism.
• The model naturally produces streaky features within the stream.
