On the Location of the Snow Line in a Protoplanetary Disk
M. Lecar, M. Podolak, D. Sasselov +1
In a protoplanetary disk, the inner edge of the region where the temperature falls below the condensation temperature of water is referred to as the 'snow line'. Outside the snow l…
Dispersing the Gaseous Protoplanetary Disc and Halting Type II Migration
M. Lecar, D. D. Sasselov
More than 30 extra-solar Jupiter-like planets have shorter periods than the planet Mercury. It is generally accepted that they formed further out, and migrated inwards. In order to…
Halting Planet Migration in the Evacuated Centers of Protoplanetary Disks
Marc J. Kuchner, Myron Lecar
Precise Doppler searches for extrasolar planets find a surfeit of planets with orbital periods of 3-4 days, and no planets with orbital periods less than 3 days. The circumstellar…
Chaos in the Solar System
M. Lecar, F. Franklin, M. Holman +1
The physical basis of chaos in the solar system is now better understood: in all cases investigated so far, chaotic orbits result from overlapping resonances. Perhaps the clearest…
On the Snow Line in Dusty Protoplanetary Disks
D. D. Sasselov, M. Lecar
The snow line, in Hayashi's (1981) model, is where the temperature of a black body that absorbed direct sunlight and re-radiated as much as it absorbed, would be 170~K. It is usual…
Halting Planetary Migration
M. Lecar, D. D. Sasselov
When Jupiter's Roche Lobe radius exceeded the scale height of the protoplanetary disk, Jupiter opened a gap in the disk. When the gap was wide enough, tidal torques from the disk i…
