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…

Relativistic Effects on Circumbinary Orbit Stability

Gonzalo C. de Elía, Macarena Zanardi, Rebecca G. Martin

With n-body simulations and analytic approximations we study the dynamics and stability of low eccentricity misaligned test particles around binary systems with varying mass fracti…

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…

Formation of super-Earths around low-mass stars: evolution of an icy dead zone

Danilo A. Arturo Rodriguez, Rebecca G. Martin

Exoplanet observations show that close-in super-Earths are more common around M-dwarfs than around solar mass stars. Since the snow line in a protoplanetary disc plays a crucial ro…
