Anotácia knihy

Over the last thirty years, substantial evidence has§accumulated suggesting that supersonic turbulence§dominates the motion of gas within molecular§star-forming clouds, and is the main factor§determining their internal density and velocity§structure.§§The present work has aimed to test the extent to§which simulations employing isothermal equation of§state correctly model the behaviour of molecular§turbulence, and investigate the impact of turbulence§on molecular dynamics. To achieve this, a numerical§scheme is constructed, which couples the most§important chemical processes with a general purpose§hydrodynamical code (ZEUS-3D). It is found that the§isothermal simulations reproduce correctly the§dynamics of the molecular turbulence, and can be used§to predict properties of the molecular emission. It§is discovered that, given the supersonic dynamics,§the chemical processes can be significantly§accelerated, implying that molecular clouds may be§undergoing both rapid dynamical and chemical changes.§§This work should be interesting to astronomers§specialising in the area of star formation, and§anyone who wants get familiar with the§star formation theory.
