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 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 ... -
The first confirmed superoutburst of the dwarf nova GALEX J215818.5+241924
Shears, Jeremy; Koff, Robert; Masi, G.; Miguel Agustino, Enrique de; Miller, Ian; Roberts, George; Sabo, Richard; Stein, William; Ulowetz, Joseph (Cornell University, 2013)
In 2011 October an optical transient was reported in Pegasus as a possible nova. The object had an ultraviolet counterpart, GALEX J215818.5+241924. In this paper we present follow-up photometry of the object which revealed ... -
The orbital and superhump periods of the dwarf nova SDSS J093249.57+472523.0
Shears, Jeremy; Brady, Steve; Dvorak, Shawn; Miguel Agustino, Enrique de; Morelle, Etienne; Oksanen, Arto; Sabo, Richard (Cornell University, 2012)
We report unfiltered CCD photometry of the eclipsing dwarf nova SDSS J093249.57+472523.0 obtained during its first confirmed outburst in 2011 March. The outburst amplitude was at least 3.0 magnitudes above mean quiescence ... -
The orbital period of the eclipsing dwarf nova SDSS J081610.84+453010.2
Shears, Jeremy; Brady, Steve; Campbell, Tut; Henden, Arne; Miguel Agustino, Enrique de; Morelle, Etienne; Roberts, George; Sabo, Richard; Miller, Ian (Cornell University, 2011)
We present time resolved photometry of the cataclysmic variable SDSS J081610.84+453010.2 and have established for the first time that it is an eclipsing dwarf nova. We observed an outburst of the system which lasted about ...
