Positive superhumps in high mass ratio cataclysmic variables driven by apsidal disk precession
Rebecca G. Martin, Stephen H. Lubow, David Vallet +1
Previously it has been assumed that a cataclysmic variable (CV) disk can only become eccentric and display superhumps if the 3:1 resonance is located within the disk. This requires…

Negative superhumps in cataclysmic variables driven by retrograde apsidal disk precession
David Vallet, Rebecca G. Martin, Stephen H. Lubow +1
Negative superhumps are photometric modulations in cataclysmic variables with periods slightly shorter than the orbital period. They are usually attributed to retrograde nodal prec…
