Low Mass Ratio Contact Binary Systems HN UMa and II UMa - III [PDF]
Journal of Astronomy and Space Sciences, 2006 We present newly observed BVRI CCD light curves for low mass ratio contact binaries, HN UMa and II UMa. The absolute dimensions of these objects were obtained by applying the Wilson-Devinney program to previously published spectroscopic analysis and to ...

Theory of Binary Boson Solutions [PDF]
Physical Review A, 1970 The properties of a dilute solution of mass-3 bosons in liquid He4 at low temperatures are computed via a variational procedure. A set of coupled integrodifferential equations is solved, yielding expressions for the ground-state energy per particle, the binding energy of He3 in He4, the (3, 3), (4, 3), and (4, 4) distribution functions, and the long ...

Restricted diffusion in binary solutions [PDF]
AIChE Journal, 1973 AbstractDiffusion coefficients of binary solutions can be measured accurately by observation at long times of isothermal diffusion in a vertical cell closed at the ends (restricted diffusion). The present analysis, which accounts for the effects of solvent flux and variable solution properties, demonstrates that the experiment yields a well‐defined ...
