An estimate of resident time of the Oort Cloud new comets in planetary region
Takashi Ito, Arika Higuchi
We describe the result of our numerical orbit simulation which traces dynamical evolution of new comets coming from the Oort Cloud. We combine two dynamical models for this purpose…
Anisotropy of Long-period Comets Explained by Their Formation Process
Arika Higuchi
Long-period comets coming from the Oort cloud are thought to be planetesimals formed in the planetary region on the ecliptic plane. We have investigated the orbital evolution of th…
Hyperbolic Orbits in the Solar System: Interstellar Origin or Perturbed Oort Cloud Comets?
Arika Higuchi, Eiichiro Kokubo
We study the dynamical properties of objects in hyperbolic orbits passing through the inner Solar system in the context of two different potential sources: interstellar space and t…
Chaos in the inert Oort cloud
Melaine Saillenfest, Marc Fouchard, Takashi Ito +1
Context: Distant trans-Neptunian objects are subject to planetary perturbations and galactic tides. The former decrease with the distance, while the latter increase. In the interme…
Speeding past planets? Asteroids radiatively propelled by giant branch Yarkovsky effects
Dimitri Veras, Arika Higuchi, Shigeru Ida
Understanding the fate of planetary systems through white dwarfs which accrete debris crucially relies on tracing the orbital and physical properties of exo-asteroids during the gi…
Formation of wide-orbit gas giants near the stability limit in multi-stellar systems
Arika Higuchi, Shigeru Ida
We have investigated the formation of a circumstellar wide-orbit gas giant planet in a multiple stellar system. We consider a model of orbital circularization for the core of a gia…
