Discovery of a Long-Lived, High Amplitude Dusty Infrared Transient
C. T. Britt, T. J. Maccarone, J. D. Green +15
We report the detection of an infrared selected transient which has lasted at least 5 years, first identified by a large mid-infrared and optical outburst from a faint X-ray source…
The Relationship Between X-ray Luminosity and Duty Cycle for Dwarf Novae and their Specific Frequency in the Inner Galaxy
C. T. Britt, T. J. Maccarone, M. L. Pretorius +9
We measure the duty cycles for an existing sample of well observed, nearby dwarf novae using data from AAVSO, and present a quantitative empirical relation between the duty cycle o…
Gemini Spectroscopy of Galactic Bulge Sources: A Population of Hidden Accreting Binaries Revealed?
Jianfeng Wu, P. G. Jonker, M. A. P. Torres +8
We present Gemini spectroscopy for 21 candidate optical counterparts to X-ray sources discovered in the Galactic Bulge Survey (GBS). For the majority of the 21 sources, the optical…
Variability of Optical Counterparts in the Chandra Galactic Bulge Survey
Christopher T. Britt, R. I. Hynes, C. B. Johnson +13
We present optical lightcurves of variable stars consistent with the positions of X-ray sources identified with the Chandra X-ray Observatory for the Chandra Galactic Bulge Survey.…
CXOGBS~J173620.2--293338: A Candidate Symbiotic X-ray Binary Associated with a Bulge Carbon Star
R. I. Hynes, M. A. P. Torres, C. O. Heinke +10
The Galactic Bulge Survey is a wide but shallow X-ray survey of regions above and below the Plane in the Galactic Bulge. It was performed using the Chandra X-ray Observatory's ACIS…
Identification of twenty-three accreting binaries in the Galactic Bulge Survey
M. A. P. Torres, P. G. Jonker, C. T. Britt +8
(Abridged:) We present the identification of optical counterparts to 23 Galactic Bulge Survey X-ray sources. We report their accurate coordinates and optical spectra acquired at th…
Photometric Survey to Search for Field sdO Pulsators
Christopher B. Johnson, E. M. Green, S. Wallace +4
We present the results of a campaign to search for subdwarf O (sdO) star pulsators among bright field stars. The motivation for this project is the recent discovery by Randall et a…
