The general relativistic Lense-Thirring effect can be detected by means of a suitable combination of orbital residuals of the laser-ranged LAGEOS and LAGEOS II satellites. While this observable is not affected by the orbital perturbation induced by the zonal Earth solid and ocean tides, it is sensible to those generated by the tesseral and sectorial tides. The assessment of their influence on t...

A novel way of looking at the evolution of star clusters is presented. With a dynamical temperature, given by the mean kinetic energy of the cluster stars, and a dynamical luminosity, which is defined as the kinetic energy of the stars leaving the cluster in analogy to the energy of photons emitted by a star, the dissolution of star clusters is studied using a new dynamical temperature-luminosi...

New Zealand is presently in the early stages of realizing its signficant marine energy resources. The potential is impressively large: this paper addresses likely developments to harness this potential. Openocean wave and tidal current resource have been modelled using hindcast techniques, resulting in an integrated suite of maps at national regional scales. Specific prospective sites have been...

We study the linear, but fully non-adiabatic tidal response of a uniformly rotating, somewhat evolved (X c = 0.4), 10 M ⊙ main sequence star to the dominant l = 2 components of its binary companion's tidal potential. This is done numerically with a 2D implicit finite difference scheme. We assume the spin vector of the 10 M ⊙ star to be aligned perpendicular to the orbital plane and calculate th...

The Gulf of Tonkin, situated in the Vietnam East Sea/South China Sea, is azone of strong ecological, touristic and economic interest. Improving ourknowledge of its hydro-sedimentary processes (transport of suspendedparticles) is of great importance. The scientific objective of this study is torevisit the dominant physical processes that characterize tidal dynamics in theGulf...

using tidal potential, the effect of tide on the gravity field, crustal deformation due to tidal force, and gravity variations resulted from the crustal deformation are presented. tidal potential is divided into constant and periodic (diurnal and semi-diurnal) constituents, and for each constituents crustal displacements in radial, south-north, and east-west directions are computed. the aforeme...

Measurements in the macro-tidal Daly Estuary show that the presence of an undular tidal bore contributed negligibly to the dissipation of tidal energy. No recirculation bubble was observed between a trough and the following wave crest in the lee waves following the undular bore. This differs to stationary undular bores in laboratory experiments at larger Froude numbers where a recirculation bub...
