摘要: While warm dense gas is prevalent around low-mass protostars, the presence of complex saturated molecules—the chemical inventory characteristic hot cores—has remained elusive in such environments. Here we report results an IRAM 30 m study molecular composition associated with protostar IRAS 16293-2422. Our observations highlight extremely rich organic this source abundant amounts O- and N-bearing molecules as formic acid, HCOOH, acetaldehyde, CH3CHO, methyl formate, CH3OCHO, dimethyl ether, CH3OCH3, acetic CH3COOH, cyanide, CH3CN, ethyl C2H5CN, propyne, CH3CCH. We compare core young stellar object those massive protostars address processes involved complexity regions star formation.
