Chemical and kinematic complexity of the very young star-forming region
  Serpens Main observed with ALMA
  The youngest low-mass protostars are known to be chemically rich, accreting
matter most vigorously, and producing the most powerful outflows. Molecules are
unique tracers of these phenomena. We use ALMA to study several outflow sources
in the Serpens Main region. The most luminous source, Ser-SMM1, shows the
richest chemical composition, but some complex molecules are also present in
S68N. No emission from complex organics is detected toward Ser-emb 8N, which is
the least luminous in the sample. We discuss whether these differences reflect
an evolutionary effect or whether they are due to different physical
structures. We also analyze the outflow structure from these young protostars
by comparing emission of CO and SiO. EHV molecular jets originating from
SMM1-a,b and Ser-emb 8N contrast with no such activity from S68N, which on the
other hand presents a complex outflow structure.
