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…
Primordial planet spin driven by boundary layer effects in a decretion disc
Rebecca G. Martin, Stephen H. Lubow, David Vallet +4
Accretion of material from a protoplanetary disc on to a forming giant planet can spin the planet up to close to its breakup rate, , where $M_{…
Formation of Be star decretion discs through boundary layer effects
Rebecca G. Martin, Stephen H. Lubow, David Vallet +3
Be stars are rapidly rotating, with angular frequency around of their Keplerian break up frequency, as a result of significant accretion during the earlier stellar evolut…
AC Her: Evidence of the first polar circumbinary planet
Rebecca G. Martin, Stephen H. Lubow, David Vallet +2
We examine the geometry of the post-asymptotic giant branch (AGB) star binary AC Her and its circumbinary disk. We show that the observations describe a binary orbit that is perpen…
Formation of super-Earths in icy dead zones around low-mass stars
David Vallet, Anna C. Childs, Rebecca G. Martin +2
While giant planet occurrence rates increase with stellar mass, occurrence rates of close-in super-Earths decrease. This is in contradiction to the expectation that the total mass…
Circumbinary disk evolution in the presence of an outer companion star
Rebecca G. Martin, Stephen Lepp, Stephen H. Lubow +3
We consider a hierarchical triple system consisting of an inner eccentric binary with an outer companion. A highly misaligned circumbinary disk around the inner binary is subject t…
Generalised warped disk equations
Rebecca G. Martin, Stephen H. Lubow, J. E. Pringle +6
The manner in which warps in accretion disks evolve depends on the magnitude of the viscosity. For small viscosity the warp evolves in a wave-like manner; for large visc…
