Shedding light on the origin of the broken misaligned circumtriple disk around GW Ori

Jeremy L. Smallwood, Stephen H. Lubow, Rebecca G. Martin +1

We revisit the origin of the observed misaligned rings in the circumtriple disk around GW Ori. Previous studies appeared to disagree on whether disk breaking is caused by the diffe…

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…

Adaptive particle refinement for compressible smoothed particle hydrodynamics

Rebecca Nealon, Daniel Price

We introduce adaptive particle refinement for compressible smoothed particle hydrodynamics (SPH). SPH calculations have the natural advantage that resolution follows mass, but this…

Short-Lived Gravitational Instability in Isolated Irradiated Discs

Sahl Rowther, Daniel J. Price, Christophe Pinte +3

Irradiation from the central star controls the temperature structure in protoplanetary discs. Yet simulations of gravitational instability typically use models of stellar irradiati…

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…

V892 Tau: A tidally perturbed circumbinary disc in a triple stellar system

Antoine Alaguero, Nicolás Cuello, François Ménard +8

V892 Tau is a young binary star surrounded by a circumbinary disc which show hints of interaction with the low-mass nearby star V892 Tau NE. The goal of this paper is to constrain…

Atmospheric characterisation and tighter constraints on the orbital misalignment of WASP-94 A b with HARPS

E. Ahrer, J. V. Seidel, L. Doyle +10

We present high spectral resolution observations of the hot Jupiter WASP-94 A b using the HARPS instrument on ESO's 3.6m telescope in La Silla, Chile. We probed for Na absorption i…

The orbit of HD 142527 B is too compact to explain many of the disc features

M. Nowak, S. Rowther, S. Lacour +3

HD 142527 A is a young and massive Herbig Ae/Be star surrounded by a highly structured disc. The disc shows numerous morphological structures, such as spiral arms, a horseshoe regi…

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…
