Free-floating planets from core accretion theory: microlensing predictions
Sizheng Ma, Shude Mao, Shigeru Ida +2
We calculate the microlensing event rate and typical time-scales for the free-floating planet (FFP) population that is predicted by the core accretion theory of planet formation. T…
Dust and gas density evolution at a radial pressure bump in protoplanetary disks
Tetsuo Taki, Masaki Fujimoto, Shigeru Ida
We investigate the simultaneous evolution of dust and gas density profiles at a radial pressure bump located in a protoplanetary disk. If dust particles are treated as test particl…
The radial dependence of pebble accretion rates: A source of diversity in planetary systems I. Analytical formulation
Shigeru Ida, Tristan Guillot, Alessandro Morbidelli
Context. The classical "planetesimal" accretion scenario for the formation of planets has recently evolved with the idea that "pebbles", centimeter- to meter-sized icy grains migra…
Analysis of terrestrial planet formation by the Grand Tack model: System architecture and tack location
R. Brasser, S. Matsumura, S. Ida +2
The Grand Tack model of terrestrial planet formation has emerged in recent years as the premier scenario used to account for several observed features of the inner solar system. It…
