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…
Gravitational instability in a planet-forming disk
Jessica Speedie, Ruobing Dong, Cassandra Hall +7
The canonical theory for planet formation in circumstellar disks proposes that planets are grown from initially much smaller seeds. The long-considered alternative theory proposes…
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…
Angular momentum transport via gravitational instability in the Elias 2-27 disc
Cristiano Longarini, Giuseppe Lodato, Cathie J. Clarke +6
Gravitational instability is thought to be one of the main drivers of angular momentum transport in young protoplanetary discs. The disc around Elias 2-27 offers a unique example o…
Weighing protoplanetary discs with kinematics: physical model, method and benchmark
Benedetta Veronesi, Cristiano Longarini, Giuseppe Lodato +4
The mass of protoplanetary discs sets the amount of material available for planet formation, determines the level of coupling between gas and dust, and possibly sets gravitational…
Probing the eccentricity in protostellar discs -- Modeling kinematics and morphologies
Enrico Ragusa, Elliot Lynch, Guillaume Laibe +2
Protostellar discs are mostly modelled as circular structures of gas and dust orbiting a protostar. However, a number of physical mechanisms, e.g. the presence of a (sub)stellar co…
Rotation curves in protoplanetary disks with thermal stratification
Paola Martire, Cristiano Longarini, Giuseppe Lodato +8
In recent years the gas kinematics probed by molecular lines detected with ALMA has opened a new window to study protoplanetary disks. High spatial and spectral resolution observat…
On the behaviour of eccentric sub-pc massive black hole binaries embedded in massive discs
Alessia Franchini, Alessandra Prato, Cristiano Longarini +1
Using the 3D smoothed particle hydrodynamics code PHANTOM, we investigate the evolution of the orbital properties of massive black hole binaries embedded in massive discs where gra…
Probing initial distributions of orbital eccentricity and disc misalignment via polar discs
Simone Ceppi, Nicolás Cuello, Giuseppe Lodato +4
In a population of multiple protostellar systems with discs, the sub-population of circumbinary discs whose orbital plane is highly misaligned with respect to the binary's orbital…
