Fractal Structure of Molecular Clouds
Compelling evidence exists to show that the structure of molecular clouds is fractal in nature. In this poster, the author reiterates that view and, in addition, asserts that not only is cloud geometry fractal, but that they also have a common characteristic they are similar in shape to the Horsehead in Orion. This shape can be described by the Julia function f(z) = z + c,where both z and c are...
متن کاملTurbulent Velocity Structure in Molecular Clouds
We compare velocity structure observed in the Polaris Flare molecular cloud at scales ranging from 0.015 pc to 20 pc to the velocity structure of a suite of simulations of supersonic hydrodynamic and MHD turbulence computed with the ZEUS MHD code. We examine different methods of characterising the structure, including a scanning-beam size-linewidth relation, structure functions, velocity and ve...
متن کاملthe role of thematic structure in comprehending spoken language
in fact this study is concerned with the relationship between the variation in thematice structure and the comprehension of spoken language. so the study focused on the following questions: 1. is there any relationship between thematic structure and the comprehension of spoken language? 2. which of the themes would have greated thematic force and be easier for the subjects to comprehend? accord...
15 صفحه اولThedynamical Structure and Evolutionofgiant Molecular Clouds
The interstellar medium ISM of galaxies contains gas that spans a wide range of physical conditions from hot X ray emitting plasma to cold molec ular gas The molecular gas is of particular importance because it is believed to be the site of all the star formation that occurs in galaxies In the Milky Way molecular gas constitutes about half the total mass of gas within the solar circle Much of t...
متن کاملProbing Molecular Clouds Their Density and Structure
Knowledge of physical conditions in molecular clouds is a prerequisite for deriving the distribution of molecular material in the Milky Way and other galaxies, understanding star formation within these dense regions, the stellar initial mass function, and appreciating the eeects of interaction of young stars with their natal environment. In this lecture, I review some of the basic techniques fo...
