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…
Impact of Stellar Superflares on Planetary Habitability
Yosuke A. Yamashiki, Hiroyuki Maehara, Vladimir Airapetian +15
High-energy radiation caused by exoplanetary space weather events from planet-hosting stars can play a crucial role in conditions promoting or destroying habitability in addition t…
Particle Number Dependence of The -Body Simulations of Moon Formation
Takanori Sasaki, Natsuki Hosono
The formation of the Moon from the circumterrestrial disk has been investigated by using -body simulations with the number of particles limited from to . We dev…
Satellitesimal Formation via Collisional Dust Growth in Steady Circumplanetary Disks
Yuhito Shibaike, Satoshi Okuzumi, Takanori Sasaki +1
The icy satellites around Jupiter are considered to have formed in a circumplanetary disk. While previous models focused on the formation of satellites starting from satellitesimal…
Ejection of iron-bearing giant-impact fragments and the dynamical and geochemical influence of the fragment re-accretion
Hidenori Genda, Tsuyoshi Iizuka, Takanori Sasaki +2
The Earth was born in violence. Many giant collisions of protoplanets are thought to have occurred during the terrestrial planet formation. Here we investigated the giant impact st…
Population synthesis of planet formation using a torque formula with dynamic effects
Takanori Sasaki, Toshikazu Ebisuzaki
Population synthesis studies into planet formation have suggested that distributions consistent with observations can only be reproduced if the actual Type I migration timescale is…
Excavation and Melting of the Hadean Continental Crust by Late Heavy Bombardment
Yuhito Shibaike, Takanori Sasaki, Shigeru Ida
No Hadean rocks have ever been found on Earth's surface except for zircons---evidence of continental crust, suggesting that Hadean continental crust existed but later disappeared.…
Formation, Habitability, and Detection of Extrasolar Moons
René Heller, Darren Williams, David Kipping +9
The diversity and quantity of moons in the Solar System suggest a manifold population of natural satellites exist around extrasolar planets. Of peculiar interest from an astrobiolo…
Measurement of the Reaction at Backward Angles
K. Hicks, T. Mibe, M. Sumihama
Cross sections for the have been measured at backward angles using linearly polarized photons in the range 1.50 to 2.37 GeV. In addition, the beam asymmetry for this…
Search for Supernova Neutrino Bursts at Super-Kamiokande
Kamiokande Collaboration, M. Ikeda, A. Takeda +2
The result of a search for neutrino bursts from supernova explosions using the Super-Kamiokande detector is reported. Super-Kamiokande is sensitive to core-collapse supernova explo…
Search for Diffuse Astrophysical Neutrino Flux Using Ultra-High-Energy Upward-Going Muons in Super-Kamiokande I
Kamiokande Collaboration, M. E. C. Swanson
Many astrophysical models predict a diffuse flux of high-energy neutrinos from active galactic nuclei and other extra-galactic sources. At muon energies above 1 TeV, the upward-goi…
