THE PARALLAX OF THE ORION NEBULA

Publications of the Astronomical Society of the Pacific, 1919
In Harvard Circular, 205, the writer obtained the value p".ooo5 for the parallax of this object. In Contributions of the Mount Wilson Solar Observatory, 147, 62, just published, Professor Kapteyn obtains the value 0^.0054 zbc/'.oocx). Since both results were deduced by practically the same method, that of comparing the brightness of the stars ...

Structure of the Orion Nebula

Publications of the Astronomical Society of the Pacific, 2001
ABSTRACT The nature of the structure of the Orion Nebula has become clearer but more complex. Quantitative application of simple photoionization theory has allowed construction of a three‐dimensional model of the main ionization front, while high‐resolution study of the flow of [O i], [O ii], [O iii], and [S iii] has allowed determination of how this ...

Hydrodynamical models of the Orion-KL Nebula

Astrophysics and Space Science, 1986
The interaction between an isotropic protostellar wind and an ambient molecular cloud is investigated by two-dimensional hydrodynamic computations. The wind-cloud interaction model is promising for explanation of the observed properties of the Orion-KL Nebula.

The spectrophotometry of the Orion Nebula

1964
NOTE: Text or symbols not renderable in plain ASCII are indicated by [...]. Abstract is included in .pdf document. The spectral range from [lamda]3600 to [lamda]11 000 has been observed in the spectra of the Orion nebula. The large amount of dust in the nebula effects the intensity of the lines, according to their wavelengths.

The radio spectrum of the Orion nebula

Astrophysics and Space Science, 1975
The radio spectrum of the Orion A (combined spectrum of both the M42 and M43 sources) is established by using more data than previous authors. The frequency range is also substantially expanded by using recent results. A peculiar feature appearing in the produced radio spectrum is discussed.
