DOI: 10.1016/j.ijimpeng.2019.103462
Abstract: Abstract Material fragmentation after a hypervelocity impact is important to predictive electro-optical and infrared (EO/IR) modeling. Successful comparisons with data require that hot, submicron fragments are generated in such impacts; however, experimental data has so… read more here.

DOI: 10.1016/j.pss.2019.06.008
Abstract: Abstract Chondrules are one of the major components of primitive meteorites. Their sphericity indicates they formed as molten fragments or droplets but conditions and mechanisms of chondrule formation remain unknown. A possible scenario is their… read more here.

DOI: 10.1126/sciadv.aav3971
Abstract: Hypervelocity impacts produce unexpected signatures such as glassy coating and hydrated features on metal-rich asteroid surfaces. Several arguments point to a larger proportion of metal-rich asteroids than that derived from spectral observations, as remnants of… read more here.
