Building bridges - The earliest times of the Solar System through the lens of
meteorites

With the development of observations of distant solar systems, we develop a
better understanding of the early stages of their evolution. Another source of
information regarding these very early stages of planetary systems can be found
closer to home within the components of chondrites. Of special interest are
Calcium-, Aluminium-rich Inclusions (CAIs). Studying these objects using
cosmochemical methods and tools (isotopes, major and trace elements...) opens a
window on the conditions that dominated their formation in the protoplanetary
disk. Here we present important results on these objects and how they could
bring constrains to the simulations and model being developed by the
astrophysics community.
