Spectral line analysis: voigt profile of a, k and g stars, general and empirical curve of growth and abundance of elements in m,f,k and g stars using lte formalism

The study of spectra has revealed properties of matter and has allowed us to understand more about the universe we live in. To the same extent, it grasps a huge variety of fields of study like physics, chemistry and astrophysics among others. By taking spectra samples (the finger print of the stellar objects), one may determine quantum effects and composition of the sample to be analyzed. Through the information inside each spectra we may determine the age of stars -wheather stars have a planetary system or are acompained by other stars (binary systems)-, or if they are the result of the evolution of early supernovas. As you may infer, the application of the study of spectra is astronomical. Throughout my work, I attend to show how to calculate abundance of chemical elements in stars.
