About This Book

This work presents a preliminary study on the distribution of intensity in stellar absorption lines, focusing on quantitative observations of broad and strong lines in the spectra of various stars. It discusses the methodology employed, including the use of objective prism spectra and microphotometry for analysis. The research highlights the significance of absorption line contours in understanding atomic structure and the physical constitution of stellar atmospheres. The findings are based on a series of spectrograms obtained from different stars, detailing the techniques used to ensure accurate measurements and the challenges faced during the analysis.

About the Author

Cecilia Payne-Gaposchkin

Cecilia Payne-Gaposchkin was a pioneering astrophysicist known for her groundbreaking work in the field of stellar atmospheres. Her influential book, "Stellar Atmospheres," laid the foundation for understanding the composition and behavior of stars. In her seminal paper, "On the Distribution of Intensity in Stellar Absorption Lines," she introduced innovative methods for analyzing stellar spectra, significantly advancing the study of astrophysics. As one of the first women to earn a Ph.D. in astronomy from Harvard University, she made substantial contributions to our understanding of the universe, and her legacy continues to inspire future generations of scientists.
