Solutions of the Oppenheimer--Volkoff Equations Inside 9/8$^{ths}$ of the Schwarzschild Radius
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1997-03)
We refine the Buchdahl 9/8 ths stability theorem for stars by describing quantitatively the behavior of solutions to the Oppenheimer–Volkoff equations when the star surface lies inside 9/8 ths of the Schwarzschild radius. ...
Population distributions in the vibrational deactivation of benzene and benzene-d6. First and second moments derived from two-color infrared fluorescence measurements
(Elsevier, 1993-09-01)
Time-resolved two-color infrared fluorescence (IRF) from highly vibrationally excited benzene and benzene-d6 has been used to determine means and variances of the excited molecule population distributions over the majority ...
Universality in the Thomas-Fermi-von Weizsäcker model of atoms and molecules
(Springer-Verlag, 1990-05)
We study the Thomas-Fermi-von Weizsäcker theory of atoms and molecules. The main result is to prove universality of the structure of very large atoms and molecules, i.e., proving that the structure converges as the nuclear ...
Ionization and Scattering for Short-Lived Potentials
(Kluwer Academic Publishers; Springer Science+Business Media, 1999-06)
We consider perturbations of a model quantum system consisting of a single bound state and continuum radiation modes. In many problems involving the interaction of matter and radiation, one is interested in the effect of ...
An Adaptively Refined Cartesian Mesh Solver for the Euler Equations
(Elsevier, 1993-01)
A method for adaptive refinement of a Cartesian mesh for the solution of the steady Euler equations is presented. The algorithm creates an initial uniform mesh and cuts the body out of that mesh. The mesh is then refined ...
A Spectral Element Basin Model for the Shallow Water Equations
(Elsevier, 1993-11)
A spectral element model is built for the shallow water equations in complex geometry. It is proved to be an efficient computational model in solving oceanic problems. In particular, the equatorial Rossby modon's reflection ...
An integral method for mixing, chemical reactions, and extinction in unsteady strained diffusion layers
(Elsevier, 1991-02)
An integral method is presented for determining the evolution of molecular mixing, finite rate chemical reactions, and local extinction in diffusion layers under the effect of an unsteady strain rate. The partial differential ...
Existence of infinitely-many smooth, static, global solutions of the Einstein/Yang-Mills equations
(Springer-Verlag, 1993-01)
We prove the existence of infinitely-many globally defined singularity-free solutions, to the EYM equations with SU (2) gauge group. The solutions are indexed by a coupling constant, have distinct winding numbers, and their ...
Alternative equations of motion for the radiating electron
(Springer-Verlag, 1995-02)
We have previously written down a simple second-order equation for the radiating electron and pointed out that its solutions are well behaved. A key feature of this equation is the presence of a term involving the time ...
A test of QCD based on 3-jet events from Z0 decays
(Elsevier, 1991-07-18)
We present a study of 43 000 3-jet events from Z0 boson decays. Both the measured jet energy distributions and the event orientation are reproduced by second order QCD. An alternative model with scalar gluons fails to ...
