Influence of the iron spin crossover in ferropericlase on the lower mantle geotherm
Juan J. Valencia-Cardona, Gaurav Shukla, Zhongqing Wu +3
The iron spin crossover in ferropericlase introduces anomalies in its thermodynamics and thermoelastic properties. Here we investigate how these anomalies can affect the lower mant…
Suprathermal electrons at Saturn's bow shock
A. Masters, A. H. Sulaiman, N. Sergis +4
The leading explanation for the origin of galactic cosmic rays is particle acceleration at the shocks surrounding young supernova remnants (SNRs), although crucial aspects of the a…
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…
Percolation of optical excitation mediated by near-field interactions
Makoto Naruse, Song-Ju Kim, Taiki Takahashi +7
Optical excitation transfer in nanostructured matter has been intensively studied in various material systems for versatile applications. Herein, we discuss the percolation of opti…
A Gap with a Deficit of Large Grains in the protoplanetary disk around TW Hya
Takashi Tsukagoshi, Hideko Nomura, Takayuki Muto +7
We report 3 au resolution imaging observations of the protoplanetary disk around TW Hya at 145 and 233 GHz with the Atacama Large Millimeter/Submillimeter Array. Our observat…
Gas velocity patterns in simulated galaxies: Observational diagnostics of spiral structure theories
Junichi Baba, Kana Morokuma-Matsui, Yusuke Miyamoto +2
There are two theories of stellar spiral arms in isolated disc galaxies that model stellar spiral arms with different longevities: quasi-stationary density wave theory, which chara…
Santa Barbara Cluster Comparison Test with DISPH
Takayuki Saitoh, Junichiro Makino
The Santa Barbara cluster comparison project (Frenk et al. Frenk+1999) revealed that there is a systematic difference between entropy profiles of clusters of galaxies obtained by E…
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…
A comparison of SPH artificial viscosities and their impact on the Keplerian disk
Natsuki Hosono, Takayuki R. Saitoh, Junichiro Makino
Hydrodynamical simulations of rotating disk play important roles in the field of astrophysical and planetary science. Smoothed Particle Hydrodynamics (SPH) has been widely used for…
Effect of turbulence on collisions of dust particles with planetesimals in protoplanetary disks
H. Homann, T. Guillot, J. Bec +3
Planetesimals in gaseous protoplanetary disks may grow by collecting dust particles. Hydrodynamical studies show that small particles generally avoid collisions with the planetesim…
The Giant Impact Simulations with Density Independent Smoothed Particle Hydrodynamics
Natsuki Hosono, Takayuki R. Saitoh, Junichiro Makino +2
At present, the giant impact (GI) is the most widely accepted model for the origin of the Moon. Most of the numerical simulations of GI have been carried out with the smoothed part…
A Pair of Giant Planets around the Evolved Intermediate-Mass Star HD 47366: Multiple Circular Orbits or a Mutually Retrograde Configuration
Bun'ei Sato, Liang Wang, Yu-Juan Liu +19
We report the detection of a double planetary system around the evolved intermediate-mass star HD 47366 from precise radial-velocity measurements at Okayama Astrophysical Observato…
Radio Emission from Red-Giant Hot Jupiters
Yuka Fujii, David S. Spiegel, Tony Mroczkowski +5
When planet-hosting stars evolve off the main sequence and go through the red-giant branch, the stars become orders of magnitudes more luminous and, at the same time, lose mass at…
Global High-resolution -body Simulation of Planet Formation I. Planetesimal Driven Migration
Junko Kominami, Hiroshi Daisaka, Junichiro Makino +1
We investigated whether outward Planetesimal Driven Migration (PDM) takes place or not in simulations when the self gravity of planetesimals is included. We performed -body simu…
