Schematic depiction of the IOM formation scenario. Grains with pristine, simple ice components (1) radially drift into the protoplanetary disk (2) and migrate to the dust trap hotspot through vertical mixing/transport (3), where heavy irradiation of the luke-warm ice results in the formation of organic macromolecular matter (4). -- astro-ph.EP

Organic macromolecular matter is the dominant carrier of volatile elements such as carbon, nitrogen, and noble gases in chondrites — the rocky building blocks from which Earth formed. How this […]

Integrated emission maps of detected transitions of CH2NH towards the G10.47+0.03, which are overlaid with the 2.34 mm continuum emission map. The contour levels are 20%, 40%, 60%, and 80% of peak flux. The cyan circle represents the synthesized beam of the integrated emission maps. -- astro-ph.GA

Detection And Prebiotic Chemistry of Possible Glycine Precursor Molecule Methylenimine Towards The Hot Molecular Core G10.47+0.03

by Keith CowingApril 19, 2024April 19, 2024

Amino acids are essential for the synthesis of protein. Amino acids contain both amine (R−NH2) and carboxylic acid (R−COOH) functional groups, which help to understand the possible formation mechanism of […]
