GodunovSPH with shear viscosity : implementation and tests
Seung-Hoon Cha, Matt A. Wood
The acceleration and energy dissipation terms due to the shear viscosity have been implemented and tested in GodunovSPH. The double summation method has been employed to avoid the…
Radiative feedback from protoplanets in self-gravitating protoplanetary discs
Sergei Nayakshin, Seung-Hoon Cha
It is well known that massive protoplanetary disc are gravitationally unstable beyond tens of AU from their parent star. The eventual fate of the self-gravitating gas clumps born i…
An alternative origin for debris rings of planetesimals
Sergei Nayakshin, Seung-Hoon Cha
Core Accretion, the most widely accepted scenario for planet formation, postulates existence of km-sized solid bodies, called planetesimals, arranged in a razor-thin disc in the ea…
The Tidal Downsizing hypothesis for planet formation and the composition of Solar System comets
Sergei Nayakshin, Seung-Hoon Cha, John Bridges
Comets are believed to be born in the outer Solar System where the temperature is assumed to have never exceeded T ~ 100 K. Surprisingly, observations and samples of cometary dust…
A numerical simulation of a "super-Earth" core delivery from ~ 100 AU to ~ 8 AU
Seung-Hoon Cha, Sergei Nayakshin
We use SPH simulations with an approximate radiative cooling prescription to model evolution of a massive and large ( AU) very young protoplanetary disc. We also model du…
Kelvin-Helmholtz instabilities with Godunov SPH
Seung-Hoon Cha, Shu-ichiro Inutsuka, Sergei Nayakshin
Numerical simulations for the non-linear development of Kelvin-Helmholtz instability in two different density layers have been performed with the particle-based method (Godunov SPH…
