A search for pre-biotic molecules in hot cores.

Abstract (from CDS):

Our aim is to better understand the complex chemistry of organic molecules in the interstellar medium, leading to the formation of pre-biotic molecules such as amino acids. We have performed a search for the pre-biotic molecules amino acetonitrile (H2NCH2CN) and vinyl acetylene (C2H3CCH) towards four northern hot core sources using the Onsala 20m telescope. We have determined upper limits to the column density of amino acetonitrile (1-4x1013cm–2) and vinyl acetylene (2-7x1014cm–2) in the observed sources. In addition, from the absence of other lines within the observed frequency band, we have further constrained the column density of oxiranecarbonitrile (c-C3H3NO) and amino-ethanol (NH2CH2CH2OH) in these sources.
