Monte Carlo Radiative Transfer Calculations for He I 1.0833um Triplet Scattering

2026 calculations model resonant scattering of He I 1.0833um triplet photons in uniform density spherical H II regions. The dataset contains results from Monte Carlo radiative transfer simulations performed by Bruce Draine, comparing models with and without dust. Specific row and column counts are not provided.

Use Cases

• Analyze the impact of dust presence on photon scattering outcomes from Monte Carlo radiative transfer models.
• Compare emission spectra results for uniform density spherical H II regions under different scattering conditions.
• Validate theoretical models of resonant scattering for the He I 1.0833um triplet using the provided simulation data.

Strengths

• Results are directly tied to a peer-reviewed, in-press 2026 publication in The Astrophysical Journal.
• Simulations cover both dust-inclusive and dust-free models for comparative analysis.
• The dataset is hosted on the Harvard Dataverse, a reputable academic data repository.

Limitations

• The dataset scope is narrowly focused on a specific physical process (He I 1.0833um triplet scattering) in a specific astrophysical environment.
• The underlying data structure, including row/column counts and file formats, is not documented.
• The dataset's utility is contingent on specialized knowledge of radiative transfer and H II region astrophysics.
