  • The complex chemistry of hot cores in Sagittarius B2(N): Influence of cosmic-ray ionization and thermal history
Astronomy

This article analyzes the chemical composition of a sample of hot molecular cores detected with ALMA in the high-mass star forming region Sgr B2(N). It shows that a cosmic-ray ionization rate enhanced by a factor 50 best reproduces the observed abundance ratios of various complex organic molecules.
