<strong>PAHs</strong> & interstellar molecules<br />
<strong>PAHs</strong> are injected by C-rich AGB<br />
stars as part of the soot formation<br />
process<br />
In the ISM, over ~100 Myr, <strong>PAHs</strong> are<br />
processed by UV photons<br />
“concentrating” the PAH family into<br />
its strongest members, the<br />
Grand<strong>PAHs</strong><br />
This process will be a source of<br />
related compounds including small<br />
hydrocarbons, rings, chains, sheets,<br />
cages, and fullerenes
