Title: The Tails of Palomar 5 & the Orphan Stream


Abstract:
Stellar streams hold the key to unravelling the secrets of galaxy formation, one of the most significant unresolved mysteries 
facing astronomers today.  Galactic archaeology relies on the study of regions of the Galaxy that have retained some record 
of its formation.  In the stellar halo lies the accreting globular cluster Palomar 5 that will be completely destroyed on its next 
passing through the plane of the Galaxy, leaving behind only a trail of stars.  Perhaps a similar fate to what has befallen the 
Orphan Stream.  Stellar streams are fossil relics of old, metal-poor stellar systems and are excellent tracers of the early 
formation history of the Galaxy as their accretion history can be resolved within a presumed shape of dark matter halo.  I will 
present our results of the chemical tagging of kinematically determined members of Palomar 5 and possible members of the 
parentless Orphan Stream.
