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…
