Stability of circumbinary orbits in misaligned triple star systems
Stephen Lepp, Rebecca G. Martin
We investigate the stability of circumbinary orbits in hierarchical triple star systems, focusing on the effects of a misaligned outer companion star. Test particles are subject to…
2D hydrodynamical simulations of Be star decretion disc formation through boundary layer effects
Madeline Overton, Zhaohuan Zhu, Rebecca G. Martin +1
Be stars are massive main-sequence stars rotating close to their breakup rate. They possess a decretion disc of material built up due to mass loss from the star, however, there is…
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…
Excitation of post-AGB Star Binary Eccentricity by Massive Polar-Aligned Circumbinary Disks
Shunquan Huang, Rebecca G. Martin, Stephen H. Lubow
Many post-AGB star binaries are observed to have relatively high orbital eccentricities (up to 0.6). Recently, AC Her was observed to have a polar-aligned circumbinary disk. We per…
Disc breaking through forced eccentricity growth
Madeline Overton, Rebecca G. Martin, Stephen H. Lubow +1
Motivated by misaligned discs observed in eccentric orbit Be/X-ray binaries, we examine the evolution of a retrograde disc around one component of an eccentric binary with hydrodyn…
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…
Retrograde discs around one component of a binary are unstable to tilting
Madeline Overton, Rebecca G. Martin, Stephen H. Lubow +1
With hydrodynamic simulations we show that a coplanar disc around one component of a binary can be unstable to global tilting when the disc orbits in a retrograde direction relativ…
