Links Between Optical and X-ray Light in Cygnus X-2
Alexander B. Igl, R. I. Hynes, K. S. O'Brien +2
We observed the low mass X-ray binary Cyg X-2 for a total of 18 nights over two observing runs in July and September of 2006, using the Otto Struve Telescope at McDonald Observator…
The Ultraviolet Spectral Energy Distributions of Quiescent Black Holes and Neutron Stars
R. I. Hynes, E. L. Robinson
We present HST/ACS ultraviolet photometry of three quiescent black hole X-ray transients: X-ray Nova Muscae 1991 (GU Mus), GRO J0422+32 (V518 Per), and X-ray Nova Vel 1993 (MM Vel)…
Millihertz Quasi-periodic Optical Oscillations in 4U 0614+091
Y. Zhang, R. I. Hynes, E. L. Robinson
We report the discovery of a 1mHz optical quasi-periodic oscillation (QPO) in the candidate ultracompact low-mass X-ray binary 4U 0614+091. The ultra-low frequency QPO has no X-ray…
A Catalog of Near Infrared Spectra from Type Ia Supernovae
G. H. Marion, P. Hoeflich, C. L. Gerardy +3
We present forty-one near infrared (NIR, 0.7-2.5 microns) spectra from normal Type Ia supernovae (SNe Ia) obtained at epochs ranging from fourteen days before to seventy-five days…
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…
