Morphological and geophysical evolution of terrestrial impact craters Open
Hyper-velocity meteorite impacts on planetary surfaces give rise to craters whose morphology evolves under the influence of external factors such as atmospheric processes, as well as internal factors including tectonics and metamorphism. O…

The source craters of the martian meteorites: Implications for the igneous evolution of Mars Open
Approximately 200 meteorites come from ~10 impact events on the surface of Mars, yet their pre-ejection locations are largely unknown. Here, we combine the results of diverse sets of observations and modeling to constrain the source crater…

Mineralogical Evidence of Sedimentary Volcanism for the Formation of the Thumbprint Terrains in Acidalia Planitia, Mars. Open
Introduction:  The Thumbprint Terrains (TT) are intriguing geological formations that can be observed in the northern plains (NP) of Mars. TT are commonly described as an alternation of parallel alignments of 10s of meters high high-a…

Binary craters on Ceres and Vesta and implications for binary asteroids  Open
Planetary surfaces present binary craters that can be associated with the synchronous impact of binary asteroids. In this work, we identify binary craters on asteroids (1) Ceres and (4) Vesta, and aim to characterize the properties (size r…

Recalibration of the lunar chronology due to spatial cratering-rate variability Open
Cratering chronologies are used to derive the history of planetary bodies and assume an isotropic flux of impactors over the entire surface of the Moon. The impactor population is largely dominated by near-Earth-objects (NEOs) since ∼3.5 b…

Lunar Surface Model Age Derivation: Comparisons Between Automatic and Human Crater Counting Using LRO‐NAC and Kaguya TC Images Open
Dating young lunar surfaces, such as impact ejecta blankets and terrains associated with recent volcanic activities, provides critical information on the recent events that shaped the surface of the Moon. Model age derivation of young or s…

Seismic Efficiency and Seismic Moment for Small Craters on Mars Formed in the Layered Uppermost Crust Open
Seismic activity generated by impacts depends on impact conditions and properties of the impact site. Here, we combined mapping of the regolith thickness with numerical impact simulations to better estimate the seismic efficiency and seism…
