Astrochemical Modelling: Practical Aspects of Microphysics in Numerical Simulations

Astrochemical Modelling: Practical Aspects of Microphysics in Numerical Simulations is a comprehensive and detailed guide to dealing with the standard problems that students and researchers face when they need to take into account astrochemistry in their models, including building chemical networks, determining the relevant processes, and understanding the theoretical challenges and the numerical limitations. The book provides chapters covering the theoretical background on the predominant areas of astrochemistry and each chapter follows the theoretical background with information on existing databases, step-by-step computational examples with solutions to recurrent problems, and an overview of the different processes and their numerical implementation. Furthermore, a section on case studies provides concrete examples of computational modelling usage for real-world applications and cases where the techniques can be applied. Astrochemical Modelling offers a detailed practical guide to implementing computation modelling in astrochemistry for introductory and more experienced astrochemists, astrophysicists and astronomers who need to implement modern numerical models or want to start developing computational models to study astronomical regions. Each chapter provides theoretical background on the concept described, followed by computational examples and tailored tutorials to allow for full understanding and replication of techniques Chapters are jointly written theoreticians and authors with direct experience on the computational implementation to provide a realistic and pragmatic approach to common problems Details up-to-date information on available databases, tools, and benchmarks for practical usage, forming a good starting point for introductory readers and a reference for actual implementation for more advanced researchers INDICE: 1.
