A new, more comprehensive model of gas–grain chemistry in hot molecular cores is
presented, in which nondiffusive reaction processes on dust-grain surfaces and in ice …

H‐atom tunneling reactions play important roles in astrochemistry, but an understanding of
these reactions is still in its infancy. The unique properties associated with quantum solid …

Context. Many molecules observed in the interstellar medium are thought to result from the
thermal desorption of ices. Parameters such as the desorption energy and pre-exponential …

Context. The chemical inventory of planets is determined by the physical and chemical
processes that govern the early phases of star formation. Nitrogen-bearing species are of …

Context. Complex organic species are known to be abundant toward low-and high-mass
protostars. No statistical study of these species toward a large sample of high-mass …

Interstellar amides have attracted significant attentions as they are potential precursors for a
wide variety of organics essential to life. However, our current understanding of their …

Context. Complex organic molecules (COMs), especially the oxygen-bearing species, have
been observed to be abundant in the gas phase toward low-mass and high-mass protostars …

Context. Peptide-like bond molecules, which can take part in the formation of proteins in a
primitive Earth environment, have been detected only towards a few hot cores and hot …

Context. Many C-, O-, and H-containing complex organic molecules (COMs) have been
observed in the interstellar medium (ISM) and their formation has been investigated in …

This work aims to constrain the abundances of interstellar amides, by searching for this
group of prebiotic molecules in the intermediate-mass protostar Serpens SMM1-a. ALMA …
