Dust From collisions: A Way To Probe The Composition Of Exo-planets?
In order to link infrared observations of dust formed during planet formation in debris disks to mid-infrared spectroscopic data of planetary materials from differentiated terrestrial and asteroidal bodies, we obtained […]

PHANGS-JWST First Results: Destruction of the PAH molecules in HII regions probed by JWST and MUSE
Polycyclic aromatic hydrocarbons (PAHs) play a critical role in the reprocessing of stellar radiation and in balancing the heating and cooling processes in the interstellar medium (ISM), but appear to […]
