Survey identifies acetamide in high-mass star-forming regions, suggesting pathways for prebiotic chemistry.

Key Points

This research aims to systematically detect acetamide in various high-mass star-forming regions to understand its significance in prebiotic chemistry.
Conducted a systematic survey of 52 hot molecular cores using ALMA Band 6 data.
Detected acetamide in ten cores, expanding the inventory of known emitters.
Calculated column densities of acetamide and compared them with formamide.
Acetamide detected with column densities ranging from (2.5 ± 0.9) × 10^14 to (1.5 ± 0.6) × 10^16 cm−2.
Abundance ratios of acetamide to formamide were found to be approximately 3–9 across sources.
Findings suggest a chemically linked formation pathway for acetamide, likely on grain surfaces.
