Laboratory Astrophysics Studies of the Evolution of Organic Matter with the COSmIC Facility.

[摘要] Understanding the origin of organic matter in astrophysical environments ranging from circumstellar (CS) outflows to diffuse and dense interstellar (IS) clouds to protoplanetary disks and planetary bodies has become a central objective in astrophysics. Experimental facilities dedicated to the formation and characterization of laboratory analogs generated under conditions relevant to the targeted environments have been developed in the past recent years. Recent advances achieved in laboratory astrophysics using COSmIC’s laboratory data in synergy with observational data will be presented. These results include the use of laboratory spectra to search for IS organic molecules and ions in astronomical spectra, the formation of laboratory analogs of CS and IS dust grains and planetary atmospheres aerosols from molecular precursors.
