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
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…
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…
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…
Polar orbits around the newly formed Earth-Moon binary system
Stephen Lepp, Rebecca G. Martin, Stanley A. Baronett
We examine the dynamics and stability of circumbinary particles orbiting around the Earth-Moon binary system. The moon formed close to the Earth (semi-major axis $a_{EM}\approx 3\,…
Relativistic Effects on Circumbinary Disk Evolution: Breaking the Polar Alignment around Eccentric Black Hole Binary Systems
Anna C. Childs, Rebecca G. Martin, C. J. Nixon +4
We study the effects of general relativity (GR) on the evolution and alignment of circumbinary disks around binaries on all scales. We implement relativistic apsidal precession of…
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…
Mergers of black hole binaries driven by misaligned circumbinary discs
Rebecca G. Martin, Stephen Lepp, Bing Zhang +2
With hydrodynamical simulations we examine the evolution of a highly misaligned circumbinary disc around a black hole binary including the effects of general relativity. We show th…
Black hole mergers driven by a captured low-mass companion
Stephen Lepp, Rebecca G. Martin, Bing Zhang
Increased eccentricity of a black hole binary leads to reduced merger times. With n-body simulations and analytic approximations including the effects of general relativity (GR), w…
