Impact of Size-dependent Grain Temperature on Gas-Grain Chemistry in Protoplanetary Disks: the case of low mass star disks
S. Gavino, A. Dutrey, V. Wakelam +7
Grain surface chemistry is key to the composition of protoplanetary disks around young stars. The temperature of grains depends on their size. We evaluate the impact of this temper…

Orbital stability of compact three-planet systems, II: Post-instability impact behaviour
Peter Bartram, Alexander Wittig, Jack J. Lissauer +2
Recent observational missions have uncovered a significant number of compact multi-exoplanet systems. The tight orbital spacing of these systems has led to much effort being applie…

Orbital stability of compact three-planet systems, I: Dependence of system lifetimes on initial orbital separations and longitudes
Jack J. Lissauer, Sacha Gavino
We explore the orbital dynamics of systems consisting of three planets, each as massive as the Earth, on coplanar, initially circular, orbits about a star of one solar mass. The in…
