Hydrodynamical models of the Orion-KL Nebula

Astrophysics and Space Science, 1986
Abstract As a possible model of the Orion KL Nebula, we investigate the interaction between isotropic stellar wind from an embedded protostar and an ambient molecular cloud by two-dimensional hydrodynamical computations. The cloud configurations are given by a certain class of equilibrium solutions for rotating axisymmetric isothermal ...

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 ...

Globules in the Orion Nebula. III. Age Range of the Stars in the Orion Nebula

Publications of the Astronomical Society of Japan, 1982
Abstract Photographic photomery of 413 stars with magnitudes of 5.0 to 16.0 distributed in an area of 30′ around the Orion Nebula was carried out. From a plot of R magnitude versus R—I color, the age of stars in the Orion Nebula region was found to range from 104 to 3×107 yr.

Dynamics of the Orion Nebula

Astrophysics and Space Science, 1968
The collision of supersonic gas streams within anHII region is studied. A system of stationary shock waves is set up. Theoretical line profiles through these shocked regions are compared with those obtained in the bright central regions of the Orion Nebula.

Macroscopic motions in the Orion nebula

Publications of the Astronomical Society of the Pacific, 1980
The paper reports on high spectral resolution scans of the lines of H-alpha, He I 5876 A, forbidden line O III 5007 A, forbidden line N II 6584 A, forbidden line S II 6717 A, and forbidden line O I which have been made at a grid of 13 points in the Orion nebula using Fabry-Perot interferometer and a 2-arcmin-diameter circular aperture. It is found that

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 ...
