Dust Processing in Protoplanetary Discs From Infall to Dispersal: the Origin of Solar System Isotopic Heterogeneities
Mark A. Hutchison, Maria Schönbächler, Lucio Mayer +1
The nucleosynthetic heterogeneity between different asteroids and planets is well established. These isotopic variations manifest themselves at the part per millions level or large…
Giant Planet Formation by Disk Instability
Ravit Helled, Oliver Schib, Christian Reinhardt +4
The disk instability (DI) model for giant planet formation remains an attractive alternative in explaining the formation of giant planets at early times, giant planets at large rad…
Disc fragmentation. II. Ejection of low mass Free Floating Planets from growing binary systems
Sergei Nayakshin, Luyao Zhang, Aleksandra ÄaloviÄ +4
Observations indicate that disc fragmentation due to Gravitational Instability (GI) is the likely origin of massive companions to stars, such as giant planets orbiting M-dwarf star…
The stochastic nature of migration of disc instability protoplanets in three-dimensional hydrodynamical and MHD simulations of fragmenting discs
Noah Kubli, Lucio Mayer, Hongping Deng +1
We present a detailed analysis of the nature of migration of protoplanetary clumps formed via disc instability in self-consistent 3D hydrodynamical (HD) and magneto-hydrodynamical…
Formation of free-floating planetary mass objects via circumstellar disk encounters
Zhihao Fu, Hongping Deng, Douglas N. C. Lin +1
The origin of planetary mass objects (PMOs) wandering in young star clusters remains enigmatic, especially when they come in pairs. They could represent the lowest-mass object form…
