Title:MOLECULAR COMPLEXITY IN PRESTELLAR CORES
Author(s):Lattanzi, Valerio
Contributor(s):Caselli, Paola
Subject(s):Astronomy
Abstract:Prestellar cores, such as L183\,(=\,L134N), are the first phase of the star formation process and the nursery of chemical complexity. Despite the lack of embedded sources, whose energy input to the cloud can complicate the analysis by permitting a wider range of gas-phase reactions to occur, and can cause the release of molecules formed on grain surface back into the gas phase, cold dark clouds exhibit a complex molecular inventory and distribution. \\ Here we present single-pointing observations of L183 performed with the IRAM 30m telescope at 3mm wavelength. The focus of the present study is to compare the chemical abundances of the detected molecular species with those found previously in L1544, a very similar astronomical environment, to study similarities and differences between these two prestellar cores. Also, our results will be put in comparison with an astrochemical model recently developed, providing a valuable test for its validity in the context of pre-stellar cores.
