Laboratoire de physique des 2 infinis - Irène Joliot-Curie (IJCLab)

ORSAY CEDEX

The Laboratoire de Physique des 2 Infinis Irène Joliot-Curie, or IJCLab, results from the merger of five laboratories (CSNSM, IMNC, IPNO, LAL and LPT) that were close to each other geographically and scientifically. IJCLab gathers about 700 people and its identity is centered on the “physique of the two infinites” and their applications, with a wealth of subjects related to these domains of physics.

From 2000 to 2006, Jean Duprat, a physicist at the CSNSM, went three times to the scientific base Concordia at the South Pole to collect micrometeorites, in order to understand, thanks to these witnesses of the first moments of the primitive solar system, how the Sun and its planets were formed 4.5 billion years ago.

On November 19, 2002, three astronomers, Jérémie Vaubaillon, Jean Duprat, and François Colas, came together to observe a rare astronomical phenomenon: a meteor shower. The Earth was passing through a cloud of dust left by the Tempel Tuttle comet in 1776. These shooting stars, actually tiny meteorites, were called the Leonids because they appeared to fall from the constellation Leo.
