A New Kind of Nova
J. L. Sokoloski, S. J. Kenyon, A. K. H. Kong +10
We performed extensive, multi-wavelength observations of the prototypical symbiotic star Z Andromedae between 2000 and 2003, during a large eruption. The rise to optical maximum oc…
The Hard Truth about Some "Soft" X-ray Transients
R. M. Bandyopadhyay, C. Brocksopp, R. P. Fender
We have accumulated multiwavelength lightcurves for eight black hole X-ray binaries which have been observed to enter a supposed ``soft X-ray transient'' outburst, but which in fac…
Outbursts of Classical Symbiotics: Multi-Wavelength Observations of the 2000-2001 Outburst of Z Andromedae
J. L. Sokoloski, S. J. Kenyon, A. K. H. Kong +11
We describe the first results from a program of multi-wavelength monitoring of symbiotic binary stars in outburst. The prototypical symbiotic star Z Andromedae was observed extensi…
An Improved Orbital Ephemeris for Cygnus X-1
C. Brocksopp, A. E. Tarasov, V. M. Lyuty +1
By accumulating all available radial velocity data and combining it with our own spectroscopy we present a new and improved ephemeris for Cygnus X-1 (V1357 Cygni/HDE226868). We ini…
