Three-dimensional gas flow in the solar nebula, which is subject to the gravity of the Sun and proto-Jupiter, is numerically calculated by using a three-dimensional hydrodynamic code - i.e., the socalled smoothed-particle method. The flow is circulating around the Sun as well as falling into a potential well of proto-Jupiter. The results for various masses of proto-Jupiter show that (1) the e-folding growth time of proto-Jupiter by accretion of the nebular gas is as short as about 300 years in stages where the mass of proto-Jupiter is 0.2 ~ 0.5 times the present Jovian mass, and that (2) proto-Jupiter begins to push away the nebular gas from the orbit of proto-Jupiter and form a gap around the orbit, when its mass is about 0.7 times the present Jovian mass. It is possible that this pushing-away process determined the present Jovian mass.read more

Distribution of accreting gas and angular momentum onto circumplanetary disks
Takayuki Tanigawa,Takayuki Tanigawa,Keiji Ohtsuki,Keiji Ohtsuki,Keiji Ohtsuki,Masahiro N. Machida +5 more
TL;DR: In this paper, the authors investigate gas accretion flow onto a circumplanetary disk from a protoplanetary disk in detail by using high-resolution three-dimensional nested-grid hydrodynamic simulations, in order to provide a basis of formation processes of satellites around giant planets.

Angular Momentum Accretion onto a Gas Giant Planet
TL;DR: In this paper, the authors investigate the acceleration of angular momentum onto a protoplanet system using three-dimensional hydrodynamical simulations and find that the gas flows onto the protoplanets in the vertical direction, crossing the shock front near the Hill radius.

The effect of a planet on the dust distribution in a 3D protoplanetary disk
TL;DR: In this article, the authors investigated the behavior of dust in protoplanetary disks under the action of gas drag in the presence of a planet and provided a framework for interpretation of coming observations and future studies of planetesimal growth.

Why Does the Earth Spin Forward
Luke Dones,Scott Tremaine +1 more
TL;DR: Analytic arguments and extensive orbital integrations are used to calculate the expected distributions of spin rate and obliquity as a function of the planetesimal mass and velocity distributions, implying that the spins of the terrestrial planets are determined by stochastic accretion.

Disk-Satellite Interactions
Peter Goldreich,Scott Tremaine +1 more
TL;DR: In this article, the authors calculate the rate at which angular momentum and energy are transferred between a disk and a satellite which orbit the same central mass, and show that substantial changes in both the structure of the disk and the orbit of Jupiter must have taken place on a time scale of a few thousand years.

Formation of the Giant Planets
TL;DR: In this paper, the structure of a gaseous envelope surrounding a protoplanet has been investigated in connection with the formation of the giant planets, and the most remarkable result is that a common relation between the core mass and the total mass holds irrespectively of the regions in the solar nebula.

TL;DR: In this article, the authors pointed out that the similarities between the giant planets (Jupiter, Saturn, Uranus, and Neptune) are superficial and revealed the individuality of these planets.

TL;DR: In this article, the authors consider the situation when the surface density of the disk changes on a scale length comparable to its thickness in a gap region, of comparable dimensions, containing the protoplanet.
