The Bardeen-Petterson effect in accreting supermassive black-hole binaries: disc breaking and critical obliquity
Rebecca Nealon, Enrico Ragusa, Davide Gerosa +2
The inspiral of supermassive black-hole binaries in gas-rich environment is driven by the presence of an accretion disc and viscous interactions tend to align the spin of the black…
Warping Away Gravitational Instabilities in Protoplanetary Discs
Sahl Rowther, Rebecca Nealon, Farzana Meru
We perform 3D SPH simulations of warped, non-coplanar gravitationally unstable discs to show that as the warp propagates through the self-gravitating disc, it heats up the disc ren…
Dust Traffic Jams in Inclined Circumbinary Protoplanetary Discs I. Morphology and Formation Theory
Hossam Aly, Jean-François Gonzalez, Rebecca Nealon +3
Gas and dust in inclined orbits around binaries experience precession induced by the binary gravitational torque. The difference in precession between gas and dust alters the radia…
GW Ori: circumtriple rings and planets
Jeremy L. Smallwood, Rebecca Nealon, Cheng Chen +4
GW Ori is a hierarchical triple star system with a misaligned circumtriple protoplanetary disc. Recent ALMA observations have identified three dust rings with a prominent gap at $1…
Chemical signatures of a warped protoplanetary disc
Alison K. Young, Richard Alexander, Catherine Walsh +3
Circumstellar discs may become warped or broken into distinct planes if there is a stellar or planetary companion with an orbit that is misaligned with respect to the disc. There i…
Formation of eccentric gas discs from sublimating or partially disrupted asteroids orbiting white dwarfs
David Trevascus, Daniel J. Price, Rebecca Nealon +3
Of the 21 known gaseous debris discs around white dwarfs, a large fraction of them display observational features that are well described by an eccentric distribution of gas. In th…
HD 143006: circumbinary planet or misaligned disc?
G. Ballabio, R. Nealon, R. D. Alexander +3
Misalignments within protoplanetary discs are now commonly observed, and features such as shadows in scattered light images indicate departure from a co-planar geometry. VLT/SPHERE…
