Stellar orbit evolution in close circumstellar disc encounters
Diego J. Muñoz, Kaitlin M. Kratter, Mark Vogelsberger +2
The formation and early evolution of circumstellar discs often occurs within dense, newborn stellar clusters. For the first time, we apply the moving-mesh code AREPO, to circumstel…
Planet-disc interaction on a freely moving mesh
Diego J. Munoz, Kaitlin M. Kratter, Volker Springel +1
General-purpose, moving-mesh schemes for hydrodynamics have opened the possibility of combining the accuracy of grid-based numerical methods with the flexibility and automatic reso…
Water/Icy Super-Earths: Giant Impacts and Maximum Water Content
Robert A. Marcus, Dimitar Sasselov, Sarah T. Stewart +1
Water-rich super-Earth exoplanets are expected to be common. We explore the effect of late giant impacts on the final bulk abundance of water in such planets. We present the result…
Minimum Radii of Super-Earths: Constraints from Giant Impacts
Robert A. Marcus, Dimitar Sasselov, Lars Hernquist +1
The detailed interior structure models of super-Earth planets show that there is degeneracy in the possible bulk compositions of a super-Earth at a given mass and radius, determine…
Collisional Stripping and Disruption of Super-Earths
Robert A. Marcus, Sarah T. Stewart, Dimitar Sasselov +1
The final stage of planet formation is dominated by collisions between planetary embryos. The dynamics of this stage determine the orbital configuration and the mass and compositio…
