Stellar properties refer to the characteristics and features of stars, including their size, temperature, luminosity, and composition. Studying stellar properties can help astronomers understand the life cycle of stars, their formation, evolution, and interactions with other stars and galaxies. Researchers use a variety of methods, such as spectroscopy, photometry, and astrometry, to measure and analyze stellar properties. By studying stellar properties, scientists can also gain insights into the fundamental processes that govern the behavior of stars and the universe as a whole.
