    • The emergence of negative superhumps in cataclysmic variables: Smoothed particle hydrodynamics simulations 

      Thomas, David M.; Wood, Matt A. (2015-04-20)
      Negative superhumps are believed to arise in cataclysmic variable systems when the accretion disk is tilted with respect to the orbital plane. Slow retrograde precession of the line-of-nodes results in a signal—the ...
