Formation and Evolution of Stars and Galaxies in the Cosmic Environment

With the advancement of astronomical observation technology, people have a deeper understanding of the formation and evolution of galaxies, but many details of our own Milky Way and other external galaxies are still unknown.Therefore, by studying the formation and orbital transformation mechanism of satellites, planets and stars, the author puts forward a new theory on the formation and evolution of stars and galaxies, thus revealing the hierarchical structure of galaxies and the formation and evolution laws of main sequence stars, red giants, white dwarfs, black dwarfs, supernovae, neutron stars, black holes and quasars.Some special phenomena in the course of star formation and evolution, such as sunspots, flares, fast radio bursts and gamma-ray bursts, have also been revealed.
