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…
