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. ...
Direct numerical simulations of fluid flow, heat transfer and phase changes
(The American Institute of Physics, 1997-01-10)
Direct numerical simulations of fluid flow, heat transfer, and phase changes are presented. The simulations are made possible by a recently developed finite difference/front tracking method based on the “one-field” formulation ...
Wave damping by a thin layer of viscous fluid
(The American Institute of Physics, 1997-05)
The rate of damping of surface gravity–capillary waves is investigated, in a system which consists of a thin layer of a Newtonian viscous fluid of thickness dd floating on a Newtonian fluid of infinite depth. The surface ...
Validation of HRDI MLT winds with meteor radars
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1997-10)
A validation study of the mesospheric and lower-thermospheric (MLT) wind velocities measured by the High-Resolution Doppler Imager (HRDI) on board the Upper-Atmosphere Research Satellite (UARS) has been carried out, comparing ...
Renormalons and 1/Q21/Q2 corrections
(The American Institute of Physics, 1997-06-15)
We argue that the appearance of the Landau pole in the running coupling of QCD introduces 1/Q21/Q2 power corrections in current correlator functions. These terms are not accounted for by the standard operator product ...
Reduced bias growth of pure-phase cubic boron nitride
(The American Institute of Physics, 1997-10-06)
We report results on an improved growth process for cubic boron nitride (c-BN) films. The films are deposited on a dc-biased silicon substrate using ion-assisted sputtering. First, we grow a BN template layer at a bias ...
The ultrahigh-peak-power laser: present and future
(Springer-Verlag, 1997-08)
to 10 20 -W/cm 2 range. With some refinements and with superior energy storage materials, even higher peak power in the petawatt range should be possible from tabletop systems. In this paper we show the ultimate achievable ...
Experimental assessment of Taylor’s hypothesis and its applicability to dissipation estimates in turbulent flows
(The American Institute of Physics, 1997-07)
Results are presented from an assessment of the applicability of Taylor’s hypothesis for approximating streamwise derivatives and obtaining dissipation estimates in turbulent flows. These are based on fully resolved ...
The intracluster gas fraction in X-ray clusters: constraints on the clustered mass density
(Blackwell Science Ltd, 1997-12-01)
The mean intracluster gas fraction of X-ray clusters within their hydrostatic regions is derived from recent observational compilations of David, Jones & Forman and White & Fabian. At radii encompassing a mean density 500 ...
X-ray studies of annealing in thin-film semiconductors
(The American Institute of Physics, 1997-07-01)
One of the most important issues in thin-film heterostructures is the nature of the interfaces. In general, their structure is likely to involve some degree of lattice strain, especially when the film is deposited on a ...
