Optical and UV Light Curves of the Accretion Disk Corona Source 4U 1822-371
A. J. Bayless, E. L. Robinson, R. I. Hynes +2
The eclipsing low-mass X-ray binary 4U is the prototypical accretion disk corona (ADC) system. We have obtained new time-resolved UV spectrograms of 4U with the Hubble Space Telesc…
Further Evidence for Variable Synchrotron Emission in XTE J1118+480 in Outburst
R. I. Hynes, E. L. Robinson, K. J. Pearson +7
We present simultaneous multicolor infrared and optical photometry of the black hole X-ray transient XTE J1118+480 during its short 2005 January outburst, supported by simultaneous…
Correlated X-ray and Optical Variability in V404 Cyg in Quiescence
R. I. Hynes, P. A. Charles, M. R. Garcia +11
We report simultaneous X-ray and optical observations of V404 Cyg in quiescence. The X-ray flux varied dramatically by a factor of >20 during a 60ks observation. X-ray variations w…
Discovery of Optical Bursts from MS1603.6+2600 = UW CrB
R. I. Hynes, E. L. Robinson, E. Jeffery
We report the discovery of several optical burst-like events from the low-mass X-ray binary MS1603.6+2600 (UW CrB). The events last for a few tens of seconds, exhibit a very fast r…
Mode identification of Pulsating White Dwarfs using the HST
S. O. Kepler, E. L. Robinson, D. Koester +3
We have obtained time-resolved ultraviolet spectroscopy for the pulsating DAV stars G226-29 and G185-32, and for the pulsating DBV star PG1351+489 with the Hubble Space Telescope F…
Interferometric Astrometry of the Detached White Dwarf - M Dwarf Binary Feige 24 Using Hubble Space Telescope Fine Guidance Sensor 3: White Dwarf Radius and Component Mass Estimates
G. F. Benedict, B. E. McArthur, O. G. Franz +14
With HST FGS 3 we have determined a parallax for the white dwarf - M dwarf interacting binary, Feige 24. The white dwarf (DA) component has an effective temperature, T_eff of appro…
