CARBON-CHAIN SPECIES IN WARM-UP MODELS
CARBON-CHAIN SPECIES IN WARM-UP MODELS
In previous warm-up chemical models of the low-mass star-forming region L1527, we investigated the evolution of carbon-chain unsaturated hydrocarbon species when the envelope temperature is slightly elevated to T ā 30 K. These models demonstrated that enhanced abundances of such species can be explained by gas-phase ionāmolecule chemistry following the ā¦
