Oxygen isotope fractionation in the Martian atmosphere induced by CO photolysis and O formation
Tatsuya Yoshida, Shohei Aoki, Hiromu Nakagawa +8
The enrichment of heavy isotopes of volatile elements in the Martian atmosphere indicates that Mars lost a large portion of its atmosphere through escape to space. Recent atmospher…
Global Constraint Principle for Microbial Growth Law
Jumpei F. Yamagishi, Tetsuhiro S. Hatakeyama
Monod's law is a widely accepted phenomenology for bacterial growth. Since it has the same functional form as the Michaelis--Menten equation for enzyme kinetics, cell growth is oft…
Community Report from the Biosignatures Standards of Evidence Workshop
Victoria Meadows, Heather Graham, Victor Abrahamsson +72
The search for life beyond the Earth is the overarching goal of the NASA Astrobiology Program, and it underpins the science of missions that explore the environments of Solar Syste…
Computation by Convective Logic Gates and Thermal Communication
Stuart Bartlett, Andrew K Gao, Yuk L Yung
We demonstrate a novel computational architecture based on fluid convection logic gates and heat flux-mediated information flows. Our previous work demonstrated that Boolean logic…
Particle-particle Particle-tree Code for Planetary System Formation with Individual Cut-off Method: GPLUM
Yota Ishigaki, Junko Kominami, Junichiro Makino +2
In a standard theory of the formation of the planets in our Solar System, terrestrial planets and cores of gas giants are formed through accretion of kilometer-sized objects (plane…
Thermal Conductivity of CaSiO Perovskite at Lower Mantle Conditions
Zhen Zhang, Dong-Bo Zhang, Kotaro Onga +4
Thermal conductivity () of mantle minerals is a fundamental property in geodynamic modeling. It controls the style of mantle convection and the time scale of the mantle and core…
Microlensed Radio Emission from Exoplanets
Yuta Shiohira, Yuka Terada, Den Mukuno +2
In this paper, we investigate the detectability of radio emission from exoplanets, especially hot Jupiters, which are magnified by gravitational microlensing. Because hot Jupiters…
SIRIUS project. I. Star formation models for star-by-star simulations of star clusters and galaxy formation
Yutaka Hirai, Michiko S. Fujii, Takayuki R. Saitoh
Most stars are formed as star clusters in galaxies, which then disperse into galactic disks. Upcoming exascale supercomputational facilities will enable performing simulations of g…
The effect of high nitrogen pressures on the habitable zone and an appraisal of greenhouse states
Ramses M. Ramirez
The habitable zone is the main tool that mission architectures utilize to select potentially habitable planets for follow up spectroscopic observation. Given its importance, the pr…
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…
Impact Ejecta near the Impact Point Observed using Ultra-high-speed Imaging and SPH Simulations, and a Comparison of the Two Methods
Takaya Okamoto, Kosuke Kurosawa, Hidenori Genda +1
High-speed impact ejecta at velocities comparable to the impact velocity are expected to contribute to material transport between planetary bodies and deposition of ejecta far from…
Earth-Like: An education & outreach tool for exploring the diversity of planets like our own
Elizabeth J. Tasker, Kana Ishimaru, Nicholas Guttenberg +1
Earth-Like is an interactive website and twitter bot that allows users to explore changes in the average global surface temperature of an Earth-like planet due to variations in the…
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
