; Krajci, Thomas; Foote, Jerry; Hambsch, Franz-Josef; Campbell, Tut; Roberts, George; Cejudo, David; Dvorak, Shawn; Vanmunster, Tonny; Koff, Robert; Skillman, David; Harvey, David; Martin, Brian; Rock, John; Boyd, David; Oksanen, Arto; Morelle, Etienne; Ulowetz, Joseph; Kroes, Anthony; Sabo, Richard; Jensen, Lasse (Oxford University Press, 2013)
We summarize the results of a 20-year campaign to study the light curves of BK Lyncis, a nova-like star strangely located below the 2-3 hour orbital period gap in the family of cataclysmic variables. Two apparent ... -
The helium-rich cataclysmic variable SBSS 1108+574
Carter, P. J.; Steeghs, D.; Miguel Agustino, Enrique de; Goff, W.; Koff, Robert; Krajci, Thomas; Marsh, T. R.; Gänsicke, B. T.; Breedt, E.; Groot, P. J.; Nelemans, G.; Roelofs, G. H. A.; Rau, A.; Koester, D.; Kupfer, T. (Oxford University Press, 2013)
We present time-resolved spectroscopy and photometry of the dwarf nova SBSS 1108+574, obtained during the 2012 outburst. Its quiescent spectrum is unusually rich in helium, showing broad, double-peaked emission lines from ... -
The 2011 February superoutburst of the dwarf nova SDSS J112003.40+663632.4
Shears, Jeremy; Brady, Steve; Krajci, Thomas; Miguel Agustino, Enrique de; Potter, Mike; Sabo, Richard; Stein, William (Cornell University, 2011)
We report unfiltered photometry of SDSS J112003.40+663632.4 during the 2011 February outburst which revealed the presence of superhumps with peak-to-peak amplitude of up to 0.22 magnitudes showing this to be an SU UMa ...
