Blue straggler stars beyond the Milky Way. IV. Radial distributions and dynamical implications
Chengyuan Li, Weijia Sun, Jongsuk Hong +3
Blue straggler stars have been proposeed as powerful indicators to measure the dynamical state of Galactic globular clusters. Here we examine for the first time if this framework o…
Observations of Spin-Down in Post-Mast-Transfer Stars and the Possibility for Blue Straggler Gyrochronology
Emily Leiner, Robert Mathieu, Natalie Gosnell +1
Blue stragglers and other mass transfer/collision products are likely born with rapid rotation rates due to angular momentum transfer during mass-transfer, merger or collisional fo…
Constraints on blue straggler formation mechanisms in Galactic globular clusters from proper motion velocity distributions
N. W. C. Leigh, T. Panurach, M. Simunovic +10
For a sample of 38 Galactic globular clusters (GCs), we confront the observed distributions of blue straggler (BS) proper motions and masses (derived from isochrone fitting) from t…
The Effect of Stellar Helium Abundance on Dynamics of Multiple Populations in Globular Clusters
Amy Fare, Jeremy Webb, Alison Sills
We incorporate a semi-analytic formula for the main sequence lifetime of helium-rich stars in N-body simulations of multiple population globular clusters to investigate how the enr…
On the Origin of Multiple Populations During Massive Star Cluster Formation
Corey S. Howard, Ralph E. Pudritz, Alison Sills +1
We investigate the possibility that multiple populations in globular clusters arise as a natural by-product of massive star-cluster formation. We use 3D radiative hydrodynamics sim…
Kinematics in Young Star Clusters and Associations with Gaia DR2
Michael A. Kuhn, Lynne A. Hillenbrand, Alison Sills +2
The Gaia mission has opened a new window into the internal kinematics of young star clusters at the sub-km/s level, with implications for our understanding of how star clusters for…
The internal rotation of globular clusters revealed by Gaia DR2
P. Bianchini, R. P. van der Marel, A. del Pino +5
Line-of-sight kinematic studies indicate that many Galactic globular clusters have a significant degree of internal rotation. However, three-dimensional kinematics from a combinati…
Dynamical evolution of stars and gas of young embedded stellar sub-clusters
Alison Sills, Steven Rieder, Jennifer Scora +2
We present simulations of the dynamical evolution of young embedded star clusters. Our initial conditions are directly derived from X-ray, infrared, and radio observations of local…
Kinematic fingerprint of core-collapsed globular clusters
P. Bianchini, J. J. Webb, A. Sills +1
Dynamical evolution drives globular clusters toward core collapse, which strongly shapes their internal properties. Diagnostics of core collapse have so far been based on photometr…
