Continuing to Hide Signatures of Gravitational Instability in Protoplanetary Discs with Planets
Sahl Rowther, Rebecca Nealon, Farzana Meru
We carry out three dimensional smoothed particle hydrodynamics simulations to study the impact of planet-disc interactions on a gravitationally unstable protoplanetary disc. We fin…
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…
