Convective Properties of Rotating Two-Dimensional Core-Collapse Supernova Progenitors
Emmanouil Chatzopoulos, Sean M. Couch, W. David Arnett +1
We explore the effects of rotation on convective carbon, oxygen, and silicon shell burning during the late stages of evolution in a 20Msun star. Using the Modules for Experiments i…
The Three Dimensional Evolution to Core Collapse of a Massive Star
Sean M. Couch, Emmanouil Chatzopoulos, W. David Arnett +1
We present the first three dimensional (3D) simulation of the final minutes of iron core growth in a massive star, up to and including the point of core gravitational instability a…
Beyond Mixing-length Theory: a step toward 321D
W. David Arnett, Casey Meakin, Maxime Viallet +3
We examine the physical basis for algorithms to replace mixing-length theory (MLT) in stellar evolutionary computations. Our 321D procedure is based on numerical solutions of the N…
Maximum-Likelihood Approach to Topological Charge Fluctuations in Lattice Gauge Theory
R. C. Brower, M. Cheng, G. T. Fleming +11
We present a novel technique for the determination of the topological susceptibility (related to the variance of the distribution of global topological charge) from lattice gauge t…
Preparing for an Explosion: Hydrodynamic Instabilities and Turbulence in Presupernovae
Nathan Smith, David Arnett
Both observations and direct numerical simulations are discordant with predictions of conventional stellar evolution codes for the latest stages of a massive star's life prior to c…
Buckling and force propagation along intracellular microtubules
Moumita Das, Alex J. Levine, F. C. MacKintosh
Motivated by recent experiments showing the buckling of microtubules in cells, we study theoretically the mechanical response of, and force propagation along elastic filaments embe…
