Proper Motions in Globular Clusters using Deconvolution of HST Images

Navtej Singh, Lisa-Marie Browne, Ray Butler

A sub-sampled deconvolution technique for crowded field photometry with the HST WFPC2 instrument was proposed by Butler (2000) and applied to search for optical counterparts to pul…

Parallel Astronomical Data Processing with Python: Recipes for multicore machines

Navtej Singh, Lisa-Marie Browne, Ray Butler

High performance computing has been used in various fields of astrophysical research. But most of it is implemented on massively parallel systems (supercomputers) or graphical proc…

Spin-orbit alignment in the very low mass binary regime: The L dwarf tight binary 2MASSW J0746425+200032AB

Leon K. Harding, Gregg Hallinan, Quinn M. Konopacky +4

Studies of solar-type binaries have found coplanarity between the equatorial and orbital planes of systems with 40 AU separation. By comparison, the alignment of the equatorial…

A MERLIN Observation of PSR B1951+32 and its associated Plerion

A. Golden, S. Bourke, G. Clyne +4

In an investigative 16 hour L band observation using the MERLIN radio interferometric array, we have resolved both the pulsar PSR B1951+32 and structure within the flat spectral ra…

A Photometric Method for estimating CNO Abundances in Globular Clusters

David Peat, Raymond Butler

Stromgren indices v and b are combined with broad-band index I, and a new index p, the short wavelength half of the v band, to estimate CN 4215A molecular absorption in a sample of…
