Enhanced Dust Emission in the HL Tau Disc: A Low-Mass Companion in Formation?
J. S. Greaves, A. M. S. Richards, W. K. M. Rice +1
We have imaged the disc of the young star HL Tau using the VLA at 1.3 cm, with 0.08" resolution (as small as the orbit of Jupiter). The disc is around half the stellar mass, assumi…
Dust filtration at gap edges: Implications for the spectral energy distributions of discs with embedded planets
W. K. M. Rice, Philip J. Armitage, Kenneth Wood +1
The spectral energy distributions (SEDs) of some T Tauri stars display a deficit of near-IR flux that could be a consequence of an embedded Jupiter-mass planet partially clearing a…
Investigating fragmentation conditions in self-gravitating accretion discs
W. K. M. Rice, G. Lodato, P. J. Armitage
The issue of fragmentation in self-gravitating gaseous accretion discs has implications both for the formation of stars in discs in the nuclei of active galaxies, and for the forma…
Planetary migration
Philip J. Armitage, W. K. M. Rice
Gravitational torques between a planet and gas in the protoplanetary disk result in orbital migration of the planet, and are likely to play an important role in the formation and e…
Quantifying orbital migration from exoplanet statistics and host metallicities
W. K. M. Rice, Philip J. Armitage
We investigate how the statistical distribution of extrasolar planets may be combined with knowledge of the host stars' metallicity to yield constraints on the migration histories…
Accelerated planetesimal growth in self-gravitating protoplanetary discs
W. K. M. Rice, G. Lodato, J. E. Pringle +2
In this paper we consider the evolution of small planetesimals in marginally stable, self-gravitating protoplanetary discs. The drag force between the disc gas and the embedded pla…
