From the reviews: "The individual chapters are all well-written and understandable by a non-expert ... . each chapter devotes a reasonable space to introducing the relevant experimental techniques and theoretical tools used to analyse the measurements. This provides an overall context to the book, making it potentially useful to (non-astrophysical) researchers performing high-resolution spectroscopy. In summary, this volume provides a significant amount of information regarding current challenges and approaches towards understanding stellar dynamics and the chemical constitution of celestial objects through the use of spectroscopy."
