Disc-planet misalignment from an unstable triple system: IRAS04125
Rebecca Nealon, Jeremy L. Smallwood, Hossam Aly +5
The IRAS01425+2902 wide binary system was recently reported to have both a young planet and a puzzling geometric arrangement, where the planet and binary both orbit edge-on, but mi…
Observational Signatures of Dust Traffic Jams in Polar-Aligning Circumbinary Disks
Jeremy L. Smallwood, Rebecca Nealon, Hsi-Wei Yen +4
Misaligned circumbinary disks will produce dust traffic jams during alignment or anti-alignment to the binary orbital plane. We conduct a hydrodynamical simulation of an initially…
Polar alignment of a dusty circumbinary disc -- II. Application to 99 Herculis
Jeremy L. Smallwood, Min-Kai Lin, Rebecca Nealon +2
We investigate the formation of dust traffic jams in polar-aligning circumbinary discs. In our first paper, we found as the circumbinary disc evolves towards a polar configuration…
Polar alignment of a dusty circumbinary disc -- I. Dust ring formation
Jeremy L. Smallwood, Min-Kai Lin, Hossam Aly +2
We investigate the formation of dust traffic jams in polar-aligning circumbinary discs. We use 3D smoothed particle hydrodynamical simulations of both gas and dust to model an init…
Orbital dynamics in the GG Tau A system: investigating its enigmatic disc
Claudia Toci, Simone Ceppi, Nicolás Cuello +6
GG Tau is one of the most studied multiple young stellar systems: GG Tau A is a hierarchical triple surrounded by a massive disc and its companion, GG Tau B, is also a binary. Desp…
The Role of Drag and Gravity on Dust Concentration in a Gravitationally Unstable Disc
Sahl Rowther, Rebecca Nealon, Farzana Meru +5
We carry out three dimensional smoothed particle hydrodynamics simulations to study the role of gravitational and drag forces on the concentration of large dust grains (St > 1) in…
WInDI: a Warp-Induced Dust Instability in protoplanetary discs
Hossam Aly, Rebecca Nealon, Jean-François Gonzalez
We identify a new dust instability that occurs in warped discs. The instability is caused by the oscillatory gas motions induced by the warp in the bending wave regime. We first de…
