Publication details for Prof David Flower

Flower, David (2007). Molecular Collisions in the Interstellar Medium. Cambridge, UK: Cambridge University Press.

Author(s) from Durham


In the interstellar medium - the space between the stars in galaxies - new stars are born from material that is replenished by the debris ejected by stars when they die. This book is a comprehensive manual for studying the collisional and radiative processes observed in the interstellar medium. This second edition has been thoroughly updated and extended to cover related topics in radiation theory. It considers the chemistry of the interstellar medium both at the present epoch and in the early Universe, and discusses the physics and chemistry of shock waves. The methods of calculation of the rates of collisional excitation of interstellar molecules and atoms are explained, emphasising the quantum mechanical method. This book will be ideal for researchers involved in the interstellar medium and star formation, and physical chemists specialising in collision theory or in the measurement of the rates of collision processes.

• Comprehensive manual for studying collisional and radiative processes in the interstellar medium • Contains an introduction to interstellar chemistry and the chemistry of the primordial gas • Introduces the dynamics of shock waves (caused by star formation) in the interstellar medium • Emphasises the quantum mechanical processes involved in interpreting the spectra of interstellar atoms and molecules.
