Leading & Trailing Spiral Arms in a Nearly Broken Protoplanetary Disc
Sahl Rowther, Rebecca Nealon, Richard Alexander +1
We perform three-dimensional smoothed particle hydrodynamics simulations to investigate the formation of spiral arms in misaligned circumbinary discs. In a nearly broken disc the m…

Dust density enhancements and the direct formation of planetary cores in gravitationally unstable discs
Ken Rice, Hans Baehr, Alison K Young +5
Planet formation via core accretion involves the growth of solids that can accumulate to form planetary cores. There are a number of barriers to the collisional growth of solids in…

Modelling a Transiting Circumbinary Disc in the HD98800 System
Amena Faruqi, Grant Kennedy, Rebecca Nealon +1
We present synthetic optical light curves of the hierarchical HD98800 quadruple system over a decade-long period when the circumbinary disc encircling the system's B binary is expe…
