Thermal evolution of a growing Mars
[1] We developed a new numerical model which can simulate the thermal history and metal-silicate separation of a growing Mars. In this model the thermal disturbance caused by planetesimal impacts isExpand

The Chicxulub Asteroid Impact and Mass Extinction at the Cretaceous-Paleogene Boundary
The Fall of the Dinosaurs According to the fossil record, the rule of dinosaurs came to an abrupt end ∼65 million years ago, when all nonavian dinosaurs and flying reptiles disappeared. SeveralExpand

Laboratory experiments of Titan tholin formed in cold plasma at various pressures: implications for nitrogen-containing polycyclic aromatic compounds in Titan haze
Titan, the largest satellite of Saturn, has a thick nitrogen /methane atmosphere with a thick global organic haze. A laboratory analogue of Titan’s haze, called tholin, was formed in an inductivelyExpand

Physical properties of ordinary chondrites
Physical properties (intrinsic and bulk densities, porosity, compressional and shear wave velocities, thermal diffusivity, and conductivity) are measured on 11 ordinary chondrites, one carbonaceousExpand

Evolution of an Impact-Generated H2O–CO2 Atmosphere and Formation of a Hot Proto-Ocean on Earth
Abstract Due to impact degassing during accretion, a hot H2O-rich proto-atmosphere was possibly formed on the growing Earth. We investigate the evolution of an impact-generated H2O–CO2 atmosphere atExpand

Distribution, origin and transport process of boulders deposited by the 2004 Indian Ocean tsunami at Pakarang Cape, Thailand
Abstract The tsunami of 2004 in the Indian Ocean transported thousands of meters-long boulders shoreward at Pakarang Cape, Thailand. We investigated size, position and long axis orientation of 467Expand

Multiple parent bodies of ordinary chondrites
Abstract Thermal histories of chondrite parent bodies are calculated from an initial state with material in a powder-like form, taking into account the effect of consolidation state on thermalExpand

The formation of an impact‐generated H2O atmosphere and its implications for the early thermal history of the Earth
During accretion of the earth by planetesimal impacts, shock degassing of volatile materials occurs, and a proto-atmosphere is formed. Once such an impact-generated atmosphere is formed, the surfaceExpand

Impact-induced atmospheres and oceans on Earth and Venus
High-velocity impacts of planetesimals onto a growing planet result in the impact-degassing of volatiles and the formation of an impact-induced atmosphere. Because of the blanketing effect of such anExpand

Early evolution of the Earth: accretion, atmosphere formation, and thermal history
Atmospheric and thermal evolution of the earth growing by planetesimal impacts was modeled by taking into account the blanketing effect of an impact-induced H2O atmosphere and the temperatureExpand
