Blue Stragglers as Stellar Collision Products: the Angular Momentum Question
Alison Sills, Tim Adams, Melvyn B. Davies
We investigate the structure and evolution of blue stragglers stars which were formed from direct stellar collisions between main sequence stars in globular clusters. In particular…
Stellar Collisions and the Interior Structure of Blue Stragglers
James C. Lombardi, Jessica Sawyer Warren, Frederic A. Rasio +2
Collisions of main sequence stars occur frequently in dense star clusters. In open and globular clusters, these collisions produce merger remnants that may be observed as blue stra…
Tests of Spurious Transport in Smoothed Particle Hydrodynamics
James C. Lombardi, Alison Sills, Frederic A. Rasio +1
We have performed a series of systematic tests to evaluate the effects of spurious transport in three-dimensional smoothed particle hydrodynamics (SPH) calculations. Our tests inve…
Structure and Evolution of Nearby Stars with Planets. I. Short-Period Systems
Eric B. Ford, Frederic A. Rasio, Alison Sills
Using the Yale stellar evolution code, we have calculated theoretical models for nearby stars with planetary-mass companions in short-period nearly circular orbits: 51 Pegasi, Tau…
The Distribution of Collisionally Induced Blue Stragglers in the Colour-Magnitude Diagram
Alison Sills, Charles D. Bailyn
A primary production mechanism for blue stragglers in globular clusters is thought to be collisionally-induced mergers, perhaps mediated by dynamical encounters involving binary st…
The Importance of Realistic Starting Models for Hydrodynamic Simulations of Stellar Collisions
Alison Sills, James C. Lombardi
We demonstrate the necessity of using realistic stellar models taken from stellar evolution codes, as opposed to polytropes, for starting models in smoothed particle hydrodynamics…
