Web33 minutes ago · These stars are blue supergiants (BSGs), and explaining the population of BSGs is a long-standing problem for stellar structure and evolution theory. The area in the HR diagram where the BSGs are found is expected to be scarcely populated due to rapid post-MS stellar evolution, but the opposite is observed [ 249 ]. WebPopulations of stars in galaxies can tell us a lot about the formation and evolution of galaxies and their various structural components. Spiral galaxies are complex systems, …
Webstellar evolution Throughout the Milky Way Galaxy (and even near the Sun itself), astronomers have discovered stars that are well evolved or even approaching extinction, or both, as well as occasional stars that must be very young or still in the process of formation. WebDescription. Evolution of Stars and Stellar Populations is a comprehensive presentation of the theory of stellar evolution and its application to the study of stellar populations …
WebThis introduction provides physicists with an understanding of binary and single star evolution, beginning with some background information on the topic. Readers of this text will understand the astrophysics behind the populations of compact object binary systems. WebAug 1, 2024 · This reveals that their stellar populations are dominated by ancient ( ≳ 10 Gyr) and metal-deficient stars 57, 74.

WebWe study the impact of galaxy mergers on stellar population profiles/gradients of early-type galaxies (ETGs) using ETGs at z < 0.055 in the Stripe 82 region of the Sloan Digital Sky Survey and MaNGA integral field unit spectroscopic data. Tidal features around ETGs, which are detected from deep coadded images, are regarded as direct observational …
WebThis book focuses on understanding the stellar populations of massive star clusters and aims to investigate the origin, evolution and properties of binary systems, their collision products, as well as the general characteristics (e.g. ages, metal content) of stellar population (s) in star clusters.
