FUV Spectroscopy of the Supersoft X-ray Binary RX J0513.9-6951
J. B. Hutchings, K. Winter, D. Crampton +2
We have obtained spectroscopy with the Far Ultraviolet Spectroscopic Explorer (FUSE) of the supersoft X-ray binary RX J0513.9-6951 over a complete binary orbital cycle. The spectra…
A New Orbital Ephemeris and Reinterpretation of Spectroscopic Data for the Supersoft X-ray Binary RX J0513.9-6951
A. P. Cowley, P. C. Schmidtke, D. Crampton +1
We have analyzed nearly eight years of MACHO optical photometry of the supersoft X-ray binary RX J0513.9-6951 and derived a revised orbital period and ephemeris. Previously publish…
Characterizing the Adaptive Optics Off-Axis Point-Spread Function - I: A Semi-Empirical Method for Use in Natural-Guide-Star Observations
E. Steinbring, S. M. Faber, S. Hinkley +11
Even though the technology of adaptive optics (AO) is rapidly maturing, calibration of the resulting images remains a major challenge. The AO point-spread function (PSF) changes qu…
The Gravitational Lens CFRS03.1077
David Crampton, David Schade, F. Hammer +3
An exquisite gravitational arc with a radius of 2.1" has been discovered around the z = 0.938 field elliptical galaxy CFRS03.1077 during HST observations of Canada-France Redshift…
