  • Ejecta from impact craters - ScienceDirect
    The ejecta model, along with the constants given in Table 3, can be used to calculate the ejecta velocity distribution for a given impact event From those follow a number of important features, including range of ejecta, regolith on small bodies, momentum magnification for asteroid deflection considerations, and so on
  • Ejecta - an overview | ScienceDirect Topics
    Ejecta refers to the outflow expelled during and shortly after the collision of two neutron stars, consisting of various components such as dynamical ejecta driven by tidal forces and shocks, as well as post-merger ejecta from processes like disk winds These components exhibit different speeds and interactions, with the majority moving at velocities between 0 1c and 0 3c AI generated
  • Ejecta - an overview | ScienceDirect Topics
    Ejecta refers to the material expelled from a target during an impact event, which can include coherent ejecta blankets, breccias, and melt rocks This material is categorized into proximal ejecta, which preserves target stratigraphy, and distal ejecta, typically composed of fine-grained rock and mineral fragments
  • Measuring ejecta characteristics and momentum transfer in experimental . . .
    The characteristics of ejecta are the crucial element in the concept of kinetic impact deflection of asteroids The mass and velocity distribution of …
  • Experimental study on the effect of target properties on high-velocity . . .
    To investigate how target material properties influence high-velocity ejecta, we conducted impact experiments using aluminum projectiles at velocities of about 7 km s −1, with serpentinite, dolerite, and pyrophyllite as targets Ejecta were impacted onto polycarbonate plates and analyzed using high-speed imaging and crater measurements
  • Ejecta distribution and momentum transfer from oblique impacts on . . .
    Ejecta scaling relationships are useful to determine the ejecta mass–velocity distribution and momentum transfer for vertical impacts scenarios other than the ones considered here
  • Precambrian impact structures and ejecta on earth: A review
    Impact cratering is an important geological process on Earth This review summarizes the state of knowledge of the Precambrian (Hadean, Archean, and P…
  • Numerical investigation of shock-induced ejecta breakup and size . . .
    Thus, the size distribution of low-velocity micro-ejecta near the free surface spans a wider range, with a tail-enhanced feature As the spatial distance from the free surface increases, corresponding to an increase in ejecta velocity, the size distribution range of the particles significantly narrows, consistent with experimental results [26]
  • Analysis of the contact compression stage and ejecta motion in oblique . . .
    A significant difference in the impact process emerges at varying angles As the impact angle decreases, the projectile’s trajectory on the target’s surface elongated, and the crater depth decreases Additionally, ejecta accumulates in the downrange direction, and both the ejecta volume and the duration of the contact compression stage
  • Quantifying 3D ejecta velocities during high-velocity impact . . .
    This study demonstrates a novel experimental technique to quantify the ejecta velocities during high-velocity impacts in 3D, thus allowing us to investigate the complexities associated with the impact cratering and ejecta process in greater detail
