Orbital Evolution of Close-in Super-Earths Driven by Atmospheric Escape
Naho Fujita, Yasunori Hori, Takanori Sasaki
The increasing number of super-Earths close to their host stars revealed a scarcity of close-in small planets with 1.5-2.0 in the radius distribution of …
N-body Simulations of Ring Formation Process around the Dwarf Planet Haumea
Iori Sumida, Yuya Ishizawa, Natsuki Hosono +1
Haumea is the only known trans-Neptunian object with a ring. The ring is in a position that causes a 3:1 spin-orbit resonance with the rotational period of Haumea, which has a tria…
Uranian Satellite Formation by Evolution of a Water Vapor Disk Generated by a Giant Impact
Shigeru Ida, Shoji Ueta, Takanori Sasaki +1
The ice-giant planet Uranus likely underwent a giant impact, given that its spin axis is tilted by 98 degrees. That its satellite system is equally inclined and prograde suggests t…
The Galilean Satellites Formed Slowly from Pebbles
Yuhito Shibaike, Chris W. Ormel, Shigeru Ida +2
It is generally accepted that the four major (Galilean) satellites formed out of the gas disk that accompanied Jupiter's formation. However, understanding the specifics of the form…
Can the Uranian Satellites Form from a Debris Disk Generated by a Giant Impact?
Yuya Ishizawa, Takanori Sasaki, Natsuki Hosono
Hydrodynamic simulations of a giant impact to proto-Uranus indicated that such an impact could tilt its rotational axis and produce a circumplanetary debris disk beyond the corotat…
Orbital Evolution of a Circumbinary Planet in a Gaseous Disk
Akihiro Yamanaka, Takanori Sasaki
Sub-Jupiter classed circumbinary planets discovered in close-in binary systems have orbits just beyond the dynamically unstable region, which is determined by the eccentricity and…
