- W91204278 abstract "Introduction: The parent bodies of differentiated meteorites such as HED meteorites and iron meteorites have been formed by the thermal evolution of the planetesimal interiors in the planetary accretion process. The thermal evolution would produce a lot of growing bodies with layered internal structure by pressure sintering, melting and gravity differentiation of the constituent materials; for example they might have an iron core- silicate mantle. The collisional fragmentation of the core-mantle bodies could have produced various types of meteorites such as stony meteorites and iron meteorites. Impact experiments and numerical simulations using homogeneous materials such as silicate have been conducted to simulate the collisional disruption of small bodies such as asteroids [e.g., 1, 2]. Also, impact experiments on iron meteorites were performed to know the collisional disruption of the iron meteorite parent bodies [3]. However, there is a shortage of previous studies on collisional phenomena of inhomogenous bodies with core-mantle structure: a small number of experiments and numerical simulations using core-mantle target were conducted to study the effect of layered structure. Some numerical simulations modeling terrestrial planets with an iron core and rocky mantle showed that the existence of a core lead different outcomes relative to those from homogenous bodies because of the difference between material properties of core and mantle [4, 5]. Also, impact experiments using silicate core-porous mantle targets were conducted to simulate rocky-layered bodies which could be formed at an initial stage of thermal evolution [6]. Okamoto and Arakawa (2008) showed the effect of the layered structure on impact fragmentation and showed energy fraction of the core and the mantle from estimation of the impact energy partitioned into the core. However, we have no data concerning the fragmentation condition of iron coresilicate mantle bodies. In this study, we conducted impact experiments on core-mantle targets with metal cores covered with porous mantle in order to study the collisional disruption of iron meteorite parent bodies. We prepared the targets with different core/target size ratios in order to simulate the various degrees of internal evolution. We obtained the impact strength, destruction mode and size distribution of impact fragments as a result of the collision. Using these results, we discuss the impact condition necessary to destruct an iron meteorite parent body from the energy fraction partitioned into the iron core." @default.
