![]() The PAHs might serve as seeds in a flame around which a soot particle forms, the scientists said.

The research could help scientists better understand how soot is formed during combustion in diesel engines and jets, a process that's poorly understood. The findings were detailed recently in the Proceedings of the National Academy of Sciences. "Our simulation shows that this type of charged PAH cluster can account for the ERE while satisfying the physical requirements necessary to survive the harsh interstellar conditions," said team member Young Min Rhee, postdoctoral fellow at the University of California, Berkeley. The glow comes from unusual clusters of PAHs that are charged and highly reactive but, at the same time, "have a stable, closed-shell electron configuration as does any stable molecule on Earth," the researchers said in a statement. The long melting process created a unique. So Gudipati and colleagues, led by Louis Allamandola at NASA's Ames Research Center, employed some fancy theoretical chemistry calculations to the problem. Those statement earrings are handmade to order from single-use carrier bags collected from the local community. In fact, the red glow seen in space doesn't occur on Earth because the nano-sized PAH clusters are very reactive and don't last long. The proto planetary Red Rectangle (RR) nebula is powered by HD 44179, a spectroscopic binary (P 318 d), in which a luminous post-asymptotic giant branch. So exotic, indeed, that they can't be recreated in a lab. "Although I had results that strongly supported the idea that PAHs had something to do with the ERE, the experimental results made it clear that if PAHs were involved, they were present in some as-yet unknown exotic form," said Murthy Gudipati, a NASA researcher also at the University of Maryland.
