DESCRIPTION:Hot Bubbles in Nebulae around Evolved Stars: probing stellar ev
 olution\nMr. Jesús Toala\n\nIn this talk we will present our most recent 
 numerical and observational results on the formation, evolution, and X-ray
  emission from hot bubbles in nebulae around evolved stars. Our studies in
 clude hot bubbles around massive and low-mass stars, e.g., Wolf-Rayet nebu
 lae and planetary nebulae. Our results show that the diffuse X-ray emissio
 n from these hot bubbles is a dynamic process that involves mixing of nebu
 lar material into the hot bubble due to hydrodynamical instabilities, phot
 oevaporation, thermal conduction, and dust cooling. The formation of these
  hot bubbles is governed by the evolution of the stellar wind parameters, 
 and its properties can be used to study stellar evolution.
