Stellar Migration by Short Lived Density Peaks Arising from Interference of Spiral Density Waves in an N-body Simulation
Justin Comparetta, Alice C. Quillen
We identify migrating stars in an N-body simulation of a Milky-Way-like disk. Outward migration can occur when a star in a low eccentricity orbit lags a short-lived local spiral ar…
Structure in phase space associated with spiral and bar density waves in an N-body galactic disk
Alice C. Quillen, Jamie Dougherty, Micaela B. Bagley +2
An N-body hybrid simulation, integrating both massive and tracer particles, of a Galactic disk is used to study the stellar phase space distribution or velocity distributions in di…
Jeans Instability in a Tidally Disrupted Halo Satellite Galaxy
Justin Comparetta, Alice C. Quillen
We use a hybrid test particle/N-body simulation to integrate 4 million massless test particle trajectories within a fully self-consistent 10^5 particle N-body simulation. The numbe…
Jeans Instability of Palomar 5's Tidal Tail
Alice C. Quillen, Justin Comparetta
Tidal tails composed of stars should be unstable to the Jeans instability and this can cause them to look like beads on a string. The Jeans wavelength and tail diameter determine t…
