When does a star cluster become a multiple star system? I. Lifetimes of equal-mass small-N systems
Nathan W. C. Leigh, Michael M. Shara, Aaron M. Geller
What is the difference between a long-lived unstable (or quasi-stable) multiple star system and a bona fide star cluster? In this paper, we present a possible framework to address…
A Highly Eccentric 3.9-Millisecond Binary Pulsar in the Globular Cluster NGC 6652
Megan E. DeCesar, Scott M. Ransom, David L. Kaplan +2
We present the Robert C. Byrd Green Bank Telescope discovery of the highly eccentric binary millisecond pulsar PSR J18353259A in the Fermi Large Area Telescope-detected globular…
Small-N collisional dynamics II: Roaming the realm of not-so-small-N
Nathan W. C. Leigh, Aaron M. Geller
We develop a formalism for calculating probabilities for the outcomes of stellar dynamical interactions, based on results from -body scattering experiments. We focus here on enc…
Different Dynamical Ages for the Two Young and Coeval LMC Star Clusters NGC 1805 and NGC 1818 Imprinted on Their Binary Populations
Aaron M. Geller, Richard de Grijs, Chengyuan Li +1
The two Large Magellanic Cloud star clusters NGC 1805 and NGC 1818 are approximately the same chronological age (~30 Myr), but show different radial trends in binary frequency. The…
Surprising dissimilarities in a newly formed pair of 'identical twin' stars
Keivan G. Stassun, Robert D. Mathieu, Phillip A. Cargile +3
The mass and chemical composition of a star are the primary determinants of its basic physical properties--radius, temperature, luminosity--and how those properties evolve with tim…
