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…
GRS 1915+105: The first three months with INTEGRAL
D. C. Hannikainen, O. Vilhu, J. Rodriguez +19
GRS 1915+105 is being observed as part of an Open Time monitoring program with INTEGRAL. Three out of six observations from the monitoring program are presented here, in addition t…
Bowen Fluorescence from Companion Stars in X-ray Binaries
J. Casares, D. Steeghs, R. I. Hynes +3
This paper will review a new technique of detecting companion stars in LMXBs and X-ray transients in outburst using the Bowen fluorescence lines at 4634-4640 Angs. These lines are…
HST Spectroscopy of the Nucleus of M33
Knox S. Long, Philip A. Charles, Guillaume Dubus
We have used Hubble Space Telescope to obtain moderate resolution 1150-5700 Ang. spectroscopy of the nucleus of M33 and a blue star ~1 arcsec NNW of the nucleus in an attempt to fi…
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…
Doppler Tomography of XTE J2123-058 and Other Neutron Star LMXBs
R. I. Hynes, P. A. Charles, C. A. Haswell +2
We describe Doppler tomography obtained in the 1998 outburst of the neutron star low mass X-ray binary (LMXB) XTE J2123-058. This analysis, and other aspects of phase-resolved spec…
