Advances in Astrophysics (AdAp) is devoted to publishing experimental and theoretical research papers in recent developments, discoveries, and theories in astronomy and astrophysics.The journal covers space astrophysics, stellar and galactic evolution, solar physics, stellar and planetary atmospheres, interstellar matter. Additional subjects include chemical composition and internal structure of stars, quasars and pulsars, developments in modern cosmology and radiative transfer. Astrophysics is the scientific study of the universe. It builds on astronomy by applying physics and chemistry to the study of planets, the sun, solar systems and other elements and phenomena of outer space. Theoretical astrophysics seeks to describe the origin of the universe as well as dark matter, black holes, the existence of the multiverse and more.
