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…
Positive superhumps in high mass ratio cataclysmic variables driven by apsidal disk precession
Rebecca G. Martin, Stephen H. Lubow, David Vallet +1
The paper uses 3D hydrodynamic simulations to show that cataclysmic variable disks can become eccentric and produce positive superhumps even when the 3:1 resonance lies outside the…
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_…
The fraction of polar aligned circumbinary disks
Ted M. Johnson, Rebecca G. Martin, Stephen Lepp +1
Circumbinary gas disks that are misaligned to the binary orbital plane evolve toward either a coplanar or a polar-aligned configuration with respect to the binary host. The preferr…
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…
Polar circumtriple planets and disks around misaligned hierarchical triple stars
Stephen Lepp, Rebecca G. Martin, Stephen H. Lubow
Observations of hierarchical triple star systems show that misalignments are common both between the angular momentum vector of the inner binary and the outer companion orbit, and…
