All chondrites accreted∼ 3.5 wt.% C in their matrices, the bulk of which was in a
macromolecular solvent and acid insoluble organic material (IOM). Similar material to IOM is …

This review presents our understanding of cometary dust at the end of 2017. For decades,
insight about the dust ejected by nuclei of comets had stemmed from remote observations …

Interplanetary dust particles and meteoroids mostly originate from comets and asteroids.
Understanding their distribution in the Solar system, their dynamical behavior and their …

Micrometeorites (MMs) recovered from surface snow near the Dome Fuji Station, Antarctica
are almost free from terrestrial weathering and contain very primitive materials, and are …

Biological Chirality describes this occurrence, its history, and early research around the
topic. The work covers analytical methods for observing the phenomenon, providing current …

This study is a multi-technique investigation of the Paris carbonaceous chondrite directly
applied on two selected 500× 500 µm² areas of a millimetric fragment, without any chemical …

Cette thèse porte sur l'analyse isotopique de poussières interplanétaires riches en carbone
(des micrométéorites ultracarbonées), pour mieux comprendre les processus de …

Dans cette thèse, nous nous intéressons à des problèmes de prévision tour après tour.
L'objectif est d'imaginer et d'appliquer des stratégies automatiques, qui tirent de l'expérience …

抄録 Primitive meteorites and planetary dusts contain organic materials extremely enriched
in deuterium (D) and/or 15 N compared with solar materials, which have been identified as …
