The fate of liquids trapped during the Earth's inner core growth
Marine Lasbleis, Mathilde Kervazo, Gael Choblet
The growth history of the inner core is inherently linked to the thermal history of the Earth. The crystallization of the inner core may have been delayed by supercooling, and went…
Enrichment of Strontium in Dwarf Galaxies
Yutaka Hirai, Shinya Wanajo, Takayuki R. Saitoh
Light trans-iron elements such as Sr serve as the key to understanding the astrophysical sites of heavy elements. Spectroscopic studies of metal-poor stars have revealed large star…
The Properties of Planetesimal Collisions under Jupiter's Perturbation and the Application to Chondrule Formation via Impact Jetting
Shoichi Oshino, Yasuhiro Hasegawa, Shigeru Wakita +1
Understanding chondrule formation provides invaluable clues about the origin of the solar system. Recent studies suggest that planetesimal collisions and the resulting impact melts…
The formation of the Martian moons
Pascal Rosenblatt, Ryuki Hyodo, Francesco C. Pignatale +5
Almost all the planets of our solar system have moons. Each planetary system has however unique characteristics. The Martian system has not one single big moon like the Earth, not…
Diverse outcomes of planet formation and composition around low-mass stars and brown dwarfs
Y. Miguel, A. Cridland, C. W. Ormel +2
The detection of Earth-size exoplanets around low-mass stars -- in stars such as Proxima Centauri and TRAPPIST-1 -- provide an exceptional chance to improve our understanding of th…
When did Life Likely Emerge on Earth in an RNA-First Process?
Steven A. Benner, Elizabeth A. Bell, Elisa Biondi +7
The widespread presence of ribonucleic acid (RNA) catalysts and cofactors in Earth's biosphere today suggests that RNA was the first biopolymer to support Darwinian evolution. Howe…
Inner Edge of Habitable Zones for Earth-sized Planets with Various Surface Water Distributions
Takanori Kodama, Hidenori Genda, Ryouta O'ishi +2
When planets receive insolation above a certain critical value called the runaway threshold, liquid surface water vaporizes completely, which forms the inner edge of the habitable…
Deep learning on butterfly phenotypes tests evolution's oldest mathematical model
Jennifer F. Hoyal Cuthill, Nicholas Guttenberg, Sophie Ledger +2
Traditional anatomical analyses captured only a fraction of real phenomic information. Here, we apply deep learning to quantify total phenotypic similarity across 2468 butterfly ph…
Photophoresis in the circumjovian disk and its impact on the orbital configuration of the Galilean satellites
Sota Arakawa, Yuhito Shibaike
Jupiter has four large regular satellites called the Galilean satellites: Io, Europa, Ganymede, and Callisto. The inner three of the Galilean satellites orbit in a 4:2:1 mean motio…
Climate simulations of early Mars with estimated precipitation, runoff, and erosion rates
Ramses M. Ramirez, Robert A. Craddock, Tomohiro Usui
The debate over the early Martian climate is among the most intriguing in planetary science. Although the geologic evidence generally supports a warmer and wetter climate, climate…
Spinning up planetary bodies by pebble accretion
R. G. Visser, C. W. Ormel, C. Dominik +1
Most major planetary bodies in the solar system rotate in the same direction as their orbital motion: their spin is prograde. Theoretical studies to explain the direction as well a…
Formation of rocky and icy planetesimals inside and outside the snow line: Effects of diffusion, sublimation and back-reaction
Ryuki Hyodo, Shigeru Ida, Sébastien Charnoz
It is important to clarify where and when rocky and icy planetesimals are formed in a viscously evolving disk. We wish to understand how local runaway pile-up of solids occurs insi…
Accelerated FDPS --- Algorithms to Use Accelerators with FDPS
Masaki Iwasawa, Daisuke Namekata, Keigo Nitadori +4
In this paper, we describe the algorithms we implemented in FDPS to make efficient use of accelerator hardware such as GPGPUs. We have developed FDPS to make it possible for many r…
Effects of a Binary Companion Star on Habitability of Tidally Locked Planets around an M-type Host Star
Ayaka Okuya, Yuka Fujii, Shigeru Ida
Planets in the "Habitable Zones" around M-type stars are important targets for characterization in future observations. Due to tidal-locking in synchronous spin-orbit rotations, th…
Pressure-induced structural dimerization in the hyperhoneycomb iridate -LiIrO at low temperatures
L. S. I. Veiga, K. Glazyrin, G. Fabbris +10
A pressure-induced collapse of magnetic ordering in -LiIrO at GPa has previously been interpreted as evidence for possible emergence of spin liquid state…
Discovery of an au-scale excess in millimeter emission from the protoplanetary disk around TW Hya
Takashi Tsukagoshi, Takayuki Muto, Hideko Nomura +10
We report the detection of an excess in dust continuum emission at 233~GHz (1.3~mm in wavelength) in the protoplanetary disk around TW~Hya revealed through high-sensitivity observa…
Theoretical Transmission Spectra of Exoplanet Atmospheres with Hydrocarbon Haze. II. Dependence on UV Irradiation Intensity, Metallicity, C/O Ratio, Eddy Diffusion Coefficient, and Temperature
Yui Kawashima, Masahiro Ikoma
Recent transmission spectroscopy has revealed that clouds and hazes are common in the atmospheres of close-in exoplanets. In this study, using the photochemical, microphysical, and…
Onset of giant planet migration before 4480 million years ago
Stephen J. Mojzsis, Ramon Brasser, Nigel M. Kelly +2
Immediately after their formation, the terrestrial planets experienced intense impact bombardment by comets, leftover planetesimals from primary accretion, and asteroids. This temp…
Possibility of Concentration of Non-volatile Species near the Surface of Comet 67P/Churyumov-Gerasimenko
Taiki Suzuki, Yoshiharu Shinnaka, Liton Majumdar +4
The cometary materials are thought to be the reservoir of primitive materials in the Solar System. The recent detection of glycine and CHNH by the ROSINA mass spectrometer…
Water delivery by pebble accretion to rocky planets in habitable zones in evolving disks
Shigeru Ida, Takeru Yamamura, Satoshi Okuzumi
The Earth's ocean mass is only 2.3 x 10^{-4} of the whole planet mass. Even including water in the interior, it would be at most 10^{-3}-10^{-2}. Ancient Mars may have had a simila…
