Faint High Latitude Carbon Stars Discovered by the Sloan Digital Sky Survey: Methods and Initial Results
Bruce Margon, Scott F. Anderson, Hugh C. Harris +5
We report the discovery of 39 Faint High Latitude Carbon Stars (FHLCs) from Sloan Digital Sky Survey commissioning data. The objects, each selected photometrically and verified spe…
The Optical Identification of the X-ray Burster X1746-370 in the Globular Cluster NGC6441
L. Homer, Scott F. Anderson, Bruce Margon +2
We find convincing observational evidence to confirm the optical identification of the X-ray burster X1746-370 located in the globular cluster NGC6441. Chandra/HRC-I imaging yields…
The Rapid Burster in Liller 1: the Chandra X-ray Position and a Search for an IR Counterpart
L. Homer, Eric W. Deutsch, Scott F. Anderson +1
Despite the unique X-ray behavior of the compact bursting X-ray source MXB1730-335, the "Rapid Burster" (RB) in the highly reddened globular cluster Liller 1, to date there has bee…
Optical Identification of the X-ray Burster in the Globular Cluster NGC1851
L. Homer, Scott F. Anderson, Bruce Margon +2
We have obtained exposures of the field of X0512-401 in the globular cluster NGC1851, in X-rays with the Chandra X-ray Observatory, and in the far-UV with the Hubble Space Telescop…
Ultracompact X-ray Binaries in Globular Clusters: Variability of the Optical Counterpart of X1832-330 in NGC 6652
Eric W. Deutsch, Bruce Margon, Scott F. Anderson
Evidence is emerging that the luminous X-ray sources in the cores of globular clusters may often consist of, or perhaps even as a class be dominated by, ultracompact (P < 1 hr) bin…
Serendipitous Discovery of a Cataclysmic Variable in the Globular Cluster NGC 6624
Eric W. Deutsch, Bruce Margon, Scott F. Anderson +1
Despite indications that classical cataclysmic variable (CV) stars are rare in globular clusters in general, and in the cluster NGC 6624 in particular, we have serendipitously disc…
Evidence for a supernova in reanalyzed optical and near-infrared images of GRB970228
T. J. Galama, N. Tanvir, P. M. Vreeswijk +14
We present B-, V-, R_c-, I_c-, J-, H-, K- and K'-band observations of the optical transient (OT) associated with GRB970228, based on a reanalysis of previously used images and unpu…
Empirical Uncertainty Estimators for Astrometry from Digital Databases
Eric W. Deutsch
In order to understand the positional uncertainties of arbitrary objects in several of the current major databases containing astrometric information, a sample of extragalactic rad…
Infrared Candidates for the Intense Galactic X-ray Source GX 17+2
Eric W. Deutsch, Bruce Margon, Scott F. Anderson +2
We present new astrometric solutions and infrared Hubble Space Telescope observations of GX 17+2 (X1813-140), one of the brightest X-ray sources on the celestial sphere. Despite 30…
A Technique for Narrowband Time Series Photometry: the X-ray Star V2116 Oph
Eric W. Deutsch, Bruce Margon, Joss Bland-Hawthorn
We have used innovative features of the Taurus Tunable Filter instrument on the 3.9-m Anglo-Australian Telescope to obtain nearly-continuous, high-throughput, linear photometry of…
A Search for the Optical Counterpart of the Luminous X-ray Source in NGC 6652
Eric W. Deutsch, Bruce Margon, Scott F. Anderson
We examine images of the field of X1832-330, the luminous (Lx ~ 10^36 erg/s) X-ray burst source near the center of the globular cluster NGC 6652, in order to identify the optical c…
The Optical Afterglow of GRB 971214: R and J Photometry
A. Diercks, E. W. Deutsch, F. J. Castander +5
We present an R-band and J-band photometry of an optical transient which is likely to be associated with the gamma-ray burst event GRB 971214. Our first measurement took place 13 h…
Complex Velocity Fields in the Shell of T Pyxidis
Bruce Margon, Eric W. Deutsch
We present spatially-resolved, moderate-resolution spectrophotometry of the recurrent nova T Pyx and a portion of the surrounding shell. The spectrum extracted from a strip of widt…
CC Bootis: QSO, Not Variable Halo Giant
Bruce Margon, Eric W. Deutsch
The poorly-studied, faint (18<m_pg<19.5) variable star CC Bootis has been noted in the literature as a candidate for a halo red giant. It proves instead to be a quasi-stellar objec…
Time-Resolved Ultraviolet Observations of the Globular Cluster X-ray Source in NGC 6624: The Shortest Known Period Binary System
Scott F. Anderson, Bruce Margon, Eric W. Deutsch +2
Using the Faint Object Spectrograph (FOS) aboard the Hubble Space Telescope, we have obtained the first time-resolved spectra of the King et al. ultraviolet-bright counterpart to t…
HST Imaging of Bright Galactic X-ray Binaries in Crowded Fields
Eric W. Deutsch, Bruce Margon, Stefanie Wachter +1
We report high spatial resolution HST imagery and photometry of three well-studied, intense galactic X-ray binaries, X2129+47, CAL 87 and GX17+2. All three sources exhibit importan…
