Stellar characterization is the study of understanding and determining the physical properties of stars, such as their temperature, mass, radius, composition, and age. This field of research involves various observational and theoretical techniques, such as spectroscopy, photometry, and stellar models, to provide insights into the nature and evolution of stars. By studying the characteristics of stars, astronomers can gain a better understanding of their formation, evolution, and behavior, as well as their influence on the surrounding environment and the broader universe. Stellar characterization is fundamental to many areas of astrophysics and is crucial for advancing our knowledge of the cosmos.
