Division G Stars and Stellar Physics


Division G is committed to fostering research on stars and stellar physics, as well as providing a forum for exchange of ideas and the distribution of key stellar data and model predictions to the research community on astrophysics. The activity of Division G is focused on the understanding of the properties of stars of all masses and evolutionary stages and the physical mechanisms that govern them. This covers a broad range of aspects, including the determination of stellar observable properties and their time variability with all possible observational techniques, the investigation of their atmospheric and internal constitution, the theoretical modeling of stellar formation, structure, and evolution, the techniques used to measure and classify stars such as spectroscopy, radial velocities and photometry, and the production of stellar predictions (e.g. stellar evolution tracks, lifetimes, chemical yields, star-planet interactions, etc) requested by the astronomical community at large. Division G is also concerned with stellar binarity and multiplicity, from close to wide systems.
