This line of research is devoted to the study of the physical processes in the interstellar medium associated with the early and late stages of the stellar evolution. These are the phases of the stellar evolution where the stars have the strongest interactions with the insterstellar/circumstellar medium trough stellar winds, outflows, and accretion of material. The main topics covered in this line are:
The early stages of star formation and radio supernovae are studied from a multiwavelength approach, making an intensive use of Radio Astronomy. That is, by sudying the radio emission from these objects both from an observational and theoretical point of view. The formation of planetary nebulae and their evolution are investigated using multiwavelength observations that cover the radio, infrared, optical, ultraviolet and X-ray spectral ranges.
