Resumen:

I will present the latest studies on the evolution of intermediate mass stars, specifically from the post-AGBs to white dwarf phase, all of which are shedding new light on these fascinating astronomical objects. It is known that intermediate mass stars undergo complex physical (and chemical) processes as they evolve from post-AGBs to white dwarfs, with significant changes in their physical properties occurring during different stages of their evolution. I will present different combinations of observational data and theoretical models used to investigate the various phenomena that occur during this evolution, such as mass loss and the formation of planetary nebulae. These studies are essential for advancing our understanding of the life cycle of stars and their contribution to the chemical enrichment of the universe. The findings from these studies may also have significant implications for our understanding of the formation and evolution of planetary systems around other stars. Overall, these latest studies provide valuable insights into the complex and intriguing processes that occur during the evolution of intermediate mass stars.
