JOYS: The [D/H] abundance derived from protostellar outflows across the Galactic disk measured with JWST

L. Francis, E. F. van Dishoeck, A. Caratti o Garatti +8

The total deuterium abundance [D/H] in the universe is set by just two processes: the creation of deuterium in Big Bang Nucleosynthesis at an abundance of [D/H]$=2.58\pm0.13\times1…
