Temperature Fluctuations Close an Eighty-Year Abundance Gap
Spatially resolved Lagoon Nebula maps reconcile oxygen estimates from collisionally excited and recombination lines.
Summary
Spatially resolved Lagoon Nebula maps reconcile oxygen estimates from collisionally excited and recombination lines.
The first spatially resolved map of both line types across the Milky Way nebula found a tight relation between the abundance discrepancy and electron-temperature differences. Using the inferred mean temperature brought the two oxygen estimates into agreement for this region.
Why it matters
Spatially resolved Lagoon Nebula maps reconcile oxygen estimates from collisionally excited and recombination lines.
