The Distance of the Orion Nebula [PDF]

open access: possiblePublications of the Astronomical Society of the Pacific, 1931
The fainter stars situated in the central part of the Orion nebula, in the immediate neighborhood of the Trapezium, form a well-marked cluster quite comparable with other galactic star clusters ; for convenience we may call it the Trapezium cluster.

The structure of the Orion nebula

Publications of the Astronomical Society of the Pacific, 1974
The Orion nebula is the best studied of all H II regions. The experimental data for this nebula are reviewed, and interpretive models of the structure of both the nebula and its environs are developed. The H II region is composed of an inner 3-min core surrounding the exciting star theta 1 C which is partially imbedded on the near side of a massive ...
