We present an overlapping domain decomposition technique for solving the Laplace-Beltrami equation on the sphere with spherical splines. We prove that the condition number of the additive Schwarz operator is bounded by O (H 2 /h 2), where H and h are the sizes of the coarse and fine meshes, respectively. In the case that the degree of the splines is even, a(More)
We report on the current status of the University of New South Wales Extrasolar Planet Search project, giving details of the methods we use to obtain millimagnitude precision photometry using the 0.5 m Automated Patrol Telescope. We use a novel observing technique to optimally broaden the PSF and thus largely eliminate photo-metric noise due to intra-pixel(More)
The energy dependence of the nonradiative electron capture cross-section is discussed in the relativistic domain. A simple analytic expression is obtained for inner-shell transitions using second-order perturbation theory. We have confirmed that the leading-order term is found to have the following energy dependence: σ ∼ E −1 ln 2 E. This is attributed to a(More)
We report on the current status of the University of New South Wales Extrasolar Planet Search project, giving details of the methods we use to obtain millimagnitude precision photometry using the 0.5-m Automated Patrol Telescope. We use a novel observing technique to optimally broaden the point spread function and thus largely eliminate photometric noise(More)
