Vertical profiling of shock attenuation at the Rochechouart impact structure, France
Meteoritics &Planetary Science, EarlyView.Abstract Rochechouart, south‐west France, is a complex impact structure. Here, we present the first report of shock barometry of quartz from what are likely parautochthonous basement units at depth, based on samples from the 2017 C.I.R.I.R drilling campaign. The crystallographic orientations of 725 sets of PDFs in 512 quartz grains in samples from four

Meteoritics &Planetary Science, EarlyView.Abstract The Campo del Cielo iron meteorite (IAB‐MG) provides a unique window into early solar system processes, particularly the formation and evolution of carbon phases in non‐magmatic iron meteorites. In this study, we conducted a systematic nanostructural investigation of three distinct graphite occurrences—cliftonite (type I), interstitial ...

Unveiling a magnetized jet from a low-mass protostar
Nature Communications, 2018 The presence of magnetic fields in protostellar jets has been predicted theoretically, but its experimental confirmation has been elusive so far. Here, the authors report the detection of SiO line polarisation in the HH 211 protostellar jet, indicative ...

Image et mesure : deux cultures aux origines de l’astrophysique française
Cahiers François Viète, 2006 In the commission preparing the 1874 transit of Venus, debates about the choice of photographic techniques are illustrative of the stakes that would come to characterize the beginning of astronomy in France over the following decades.

Small but mighty: Impact hazards from iron Near‐Earth Objects
Meteoritics &Planetary Science, EarlyView.Abstract Small asteroids can impact Earth unexpectedly, as demonstrated by the Chelyabinsk event in 2013. The warning times are likely to be short, and the first tools for fast hazard predictions have been developed in the last years for encounters with rocky or cometary objects, which quickly fragment in the atmosphere and cause airbursts. However, in

A geophysical investigation of the Roter Kamm impact crater, Namibia
Meteoritics &Planetary Science, EarlyView.Abstract The Roter Kamm impact crater is located in the southern Namib Desert. The crater has a diameter of 2.5 km and belongs to the category of simple, bowl‐shaped impact craters, with an elevated rim of fractured target rock. The crater's interior is completely buried beneath sediments, preventing extensive surface investigations of the bedrock ...

Identification of subsurface cavities in urban environment
Scientific ReportsGravimetry is the most suitable geophysical method for identifying subsurface cavities in urban or industrial environments, as it is unaffected by nearby electromagnetic disturbances.
