Discs and Planetary Formation

ArXiv astro-ph/9810027 (1998)

Authors:

J Papaloizou, C Terquem, R Nelson

Abstract:

The formation, structure and evolution of protoplanetary discs is considered. The formation of giant planets within the environment of these models is also discussed.

Tidally-induced warps in protostellar discs

ArXiv astro-ph/9810014 (1998)

Authors:

C Terquem, J Papaloizou, R Nelson

Abstract:

We review results on the dynamics of warped gaseous discs. We consider tidal perturbation of a Keplerian disc by a companion star orbiting in a plane inclined to the disc. The perturbation induces the precession of the disc, and thus of any jet it could drive. In some conditions the precession rate is uniform, and as a result the disc settles into a warp mode. The tidal torque also leads to the truncation of the disc, to the evolution of the inclination angle (not necessarily towards alignment of the disc and orbital planes) and to a transport of angular momentum in the disc. We note that the spectral energy distribution of such a warped disc is different from that of a flat disc. We conclude by listing observational effects of warps in protostellar discs.
