Formation of Free-Floating Planets via Ejection: Population Synthesis with a Realistic IMF and Comparison to Microlensing Observations
Kangrou Guo, Shigeru Ida, Masahiro Ogihara
Microlensing observations suggest that the mass distribution of free-floating planets (FFPs) follows a declining power-law with increasing mass. The origin of such distribution is…

A Population Synthesis Study on the Formation of Cold Jupiters from Truncated Planetesimal Disks
Kangrou Guo, Masahiro Ogihara, Shigeru Ida +3
The occurrence rate of giant planets increases with orbital period and turns over at a location that roughly corresponds to the snow line of solar-type stars. Further, the density…
