Optical and X-Ray Observations of GRB 060526: A Complex Afterglow Consistent with An Achromatic Jet Break
X. Dai, J. P. Halpern, N. D. Morgan +5
We obtained 98 R-band and 18 B, r', i' images of the optical afterglow of GRB 060526 (z=3.21) with the MDM 1.3m, 2.4m, and the PROMPT telescopes in Cerro Tololo over the 5 nights f…
Superhumps in Cataclysmic Binaries. XXV. q_crit, epsilon(q), and Mass-Radius
Joseph Patterson, Jonathan Kemp, David Harvey +17
We report on successes and failures in searching for positive superhumps in cataclysmic variables, and show the superhumping fraction as a function of orbital period. Basically, al…
The Dwarf Nova PQ Andromedae
Joseph Patterson, John Thorstensen, Eve Armstrong +2
We report a photometric study of the WZ Sagittae-type dwarf nova PQ Andromedae. The light curve shows strong (0.05 mag full amplitude) signals with periods of 1263(1) and 634(1) s,…
Is FIRST J102347.6+003841 Really a Cataclysmic Binary?
J. R. Thorstensen, E. Armstrong
The radio source FIRST J102347.6+003841 was presented as the first radio-selected cataclysmic. In the discovery paper, Bond et al. (2002) show a spectrum consistent with a magnetic…
High Speed Photometry of SDSS J013701.06-091234.9
M. L. Pretorius, P. A. Woudt, B. Warner +3
We present high speed photometry of the Sloan Digital Sky Survey cataclysmic variable SDSS J013701.06-091234.9 in quiescence and during its 2003 December superoutburst. The orbital…
Rapid Oscillations in Cataclysmic Variables. XVI. DW Cancri
Joseph Patterson, John Thorstensen, Tonny Vanmunster +7
We report photometry and spectroscopy of the novalike variable DW Cancri. The spectra show the usual broad H and He emission lines, with an excitation and continuum slope character…
