The Spur and the Gap in GD-1: Dynamical evidence for a dark substructure in the Milky Way halo
Ana Bonaca, David W. Hogg, Adrian M. Price-Whelan +1
We present a model for the interaction of the GD-1 stellar stream with a massive perturber that naturally explains many of the observed stream features, including a gap and an off-…
They Might Be Giants: An Efficient Color-Based Selection of Red Giant Stars
Charlie Conroy, Ana Bonaca, Rohan P. Naidu +4
We present a color-based method for identifying red giants based on Pan-STARRS grz and WISE W1 and W2 photometry. We utilize a subsample of bright stars with precise parallaxes fro…
Off the beaten path: Gaia reveals GD-1 stars outside of the main stream
Adrian M. Price-Whelan, Ana Bonaca
Tidally-disrupted globular clusters are transformed into thin, dynamically-cold streams of stars that are extremely valuable tracers of the large- and small-scale distribution of m…
The information content in cold stellar streams
Ana Bonaca, David W. Hogg
Cold stellar streams---produced by tidal disruptions of clusters---are long-lived, coherent dynamical features in the halo of the Milky Way. Due to their different ages and differe…
Investigating the Metallicity-Mixing Length Relation
Lucas S. Viani, Sarbani Basu, Joel J. M. Ong +2
Stellar models typically use the mixing length approximation as a way to implement convection in a simplified manner. While conventionally the value of the mixing length parameter,…
