Survival of Molecular Complexity under Recent Supernova Feedback: Detection of Hot Cores in RX J1713.7-3946

Hidetoshi Sano, Kenji Furuya, Takashi Shimonishi, Yoko Oya

Hot cores inside a supernova remnant retain the same molecular ratios as those in ordinary star-forming regions.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

the column density ratios of complex organic molecules (HCOOCH3/CH3OH, CH3OCH3/CH3OH, and CH3CHO/CH3OH), a deuterated molecule (CH2DOH/CH3OH), and sulfur- and nitrogen-bearing species (OCS/CH3OH and C2H5CN/CH3CN) in HC1 are indistinguishable from those observed in hot cores/corinos in more typical star-forming environments.

C2weakest assumption

The elapsed time since the onset of exposure to high-energy particles and photons may be too short for the chemical composition of the hot core to be significantly altered, and/or the hot-core region may be shielded by magnetic fields amplified by supernova feedback, which could suppress the penetration of enhanced cosmic rays.

C3one line summary

Hot cores in supernova remnant RX J1713.7-3946 exhibit column density ratios of complex organics, deuterated species, and S/N-bearing molecules that are indistinguishable from those in typical star-forming environments.
