Have protoplanetary discs formed planets
It has recently been noted that many discs around T Tauri stars appear to comprise only a few Jupiter masses of gas and dust. Using millimetre surveys of discs within six local star formation regions, we confirm this result, and find that only a few per cent of young stars have enough circumstellar material to build gas giant planets, in standard core accretion models. Since the frequency of ob...
متن کاملOn the evolution of eccentric and inclined protoplanets embedded in protoplanetary disks
Context. Young planets embedded in their protoplanetary disk interact gravitationally with it leading to energy and angular momentum exchange. This interaction determines the evolution of the planet through changes to the orbital parameters. Aims. We investigate changes in the orbital elements of a 20 Earth–mass planet due to the torques from the disk. We focus on the non-linear evolution of in...
متن کاملThree-dimensional calculations of high and low-mass planets embedded in protoplanetary discs
We analyse the non-linear, three-dimensional response of a gaseous, viscous protoplanetary disc to the presence of a planet of mass ranging from one Earth mass (1 M⊕) to one Jupiter mass (1 MJ) by using the ZEUS hydrodynamics code. We determine the gas flow pattern, and the accretion and migration rates of the planet. The planet is assumed to be in a fixed circular orbit about the central star....
متن کاملPhotoevaporation of protoplanetary discs II : evolutionary models and observable properties
We present a new model for protoplanetary disc evolution. This model combines viscous evolution with photoevaporation of the disc, in a manner similar to Clarke, Gendrin & Sotomayor (2001). However in a companion paper (Alexander, Clarke & Pringle 2006a) we have shown that at late times such models must consider the effect of stellar radiation directly incident on the inner disc edge, and here ...
متن کاملPrecession of Inclined Rings
Differential precession due to the planet's quadrupole moment tends to destroy the alignment of particles in inclined rings. We propose that alignment is maintained by the self-gravity of the ring. This hypothesis predicts that 8i/8a>0 across the ring. If 8i/i0 <(1, 8e/e0 <(1, a8i/8a<(1, and a8e/8a< 1, a further prediction is that 8i/i0 = 8e/e0 • The a and /3 rings of Uranus may be used to test...
