Título: Detectability of Glycine in Solar-type System Precursors

Resumen: Pre-biotic molecules such as amino acids have extensively been searched for in the interstellar medium during several decades. Glycine (NH2CH2COOH) and other amino acids have indeed been found in meteorites and comets, suggesting that these organic compounds may have an interstellar origin. However, observational studies performed in molecular clouds (in particular, in massive star forming regions) have not yielded any firm detection. In this seminar, I will present simple radiative transfer calculations of glycine in a Solar-type system precursor, the L1544 pre-stellar core, which show that the detection of amino acids and other complex pre-biotic species could be feasible at the earliest stages in the formation of Solar-type systems with near-future instrumentation. This offers the possibility to make the connection between the pre-biotic chemistry in the interstellar medium and its subsequent delivery onto protoplanetary systems.
