Accretion of Terrestrial Planets from Oligarchs in a Turbulent Disk
Masahiro Ogihara, Shigeru Ida, Alessandro Morbidelli
We have investigated the final accretion stage of terrestrial planets from Mars-mass protoplanets that formed through oligarchic growth in a disk comparable to the minimum mass sol…
Simulating planet migration in globally evolving disks
A. Crida, A. Morbidelli, F. Masset
Numerical simulations of planet-disk interactions are usually performed with hydro-codes that -- because they consider only an annulus of the disk, over a 2D grid -- can not take i…
The Size-Frequency Distribution of Dormant Jupiter Family Comets
Kathryn Whitman, Alessandro Morbidelli, Robert Jedicke
We estimate the total number and the slope of the size frequency distribution (SFD) of dormant Jupiter Family Comets (JFCs) by fitting a one-parameter model to the known population…
Surface density jumps as planet traps
F. Masset, A. Morbidelli, A. Crida +1
[Abridged] The tidal torque exerted by a protoplanetary disk with power law surface density and temperature profiles onto an embedded protoplanetary embryo is generally a negative…
