Description

ALMA-DOT is a small campaign devoted to the chemical characterization of disk-outflow sources in Taurus. The sample currently consists of six Class I sources known to drive powerful outflows. The high angular resolution and sensitivity of ALMA allowed us to characterize their chemical composition by separating the disk emission from the outflow and envelope contamination. Six molecules - from carbon monoxyde to the simple organic formaldehyde and methanol - have been surveyed in each target. I present the results of the survey, shedding light on (i) the timescale for the formation of dust and gas sub-structures, (ii) the morphological interplay of dust and gas, (iii) the role of disk-feeding filaments, (iv) the distribution and formation mechanism of simple organic molecules, and (v) the chemical composition of molecular outflows. Young sources like those probed by ALMA-DOT offer the best laboratory to study how soon are planets formed and how are complex molecules delivered to the (assembling) planetary atmospheres.
