Anticenter Stream: Composition, Old Stars

Anticenter Stream: Composition Old Stars by Steven Kemper

Program Note

Anticenter Stream, composition: Old Stars was written in collaboration with astronomer Jeff Carlin, who’s research focuses on the streams of stars left behind by these dwarf galaxies when they venture too close to our much more massive Milky Way galaxy. One of these streams, known as the Anticenter Stream, was thought to be part of a much larger ring of stars, but Jeff has shown that it is likely a distinct entity. This discovery adds to our understanding of how large galaxies like the Milky Way are built up over time. Kemper’s composition, Anticenter Stream, composition: Old Stars is a meditation on Carlin’s research as well as astronomy’s role in explaining the construction of the universe.
