Application for a Novel Perturbation Expansion Method

open access: yesJournal of Algorithms & Computational Technology, 2009
We formulate a coupled vibration problem between a structure and an acoustic field by FEM (finite element methods). The problem leads to a nonstandard eigenvalue problem.

Active Carbon and Oxygen Shell Burning Hydrodynamics

open access: yes, 2006
We have simulated 2.5$\times10^3$ s of the late evolution of a $23 \rm M_\odot$ star with full hydrodynamic behavior. We present the first simulations of a multiple-shell burning epoch, including the concurrent evolution and interaction of an oxygen and ...
