GENESIS is coordinated with the proyect “Pérdida de masa, envolturas circunestelares, y el rol de las binarias en estrellas evolucionadas – EVENTs“, (PID2019-105203GB-C21), PI: J. Alcolea (OAN, Spain) y V. Bujarrabal (OAN, Spain).
Our more general objective is to study the physical and chemical properties of gas and dust envelopes around evolved low- and intermediate-mass stars in the red giant phase (AGB) and beyond, both in the planetary nebula (PN) stage and in the transition phase between the two (called post-AGB or pre-PN). We aim to advance in the identification of the processes responsible for the morphological, dynamical and chemical changes induced in the circumstellar material during the short transition stage from AGB to PN. Our research is based on multi-wavelength observations obtained with first-line telescopes (such as ALMA, HST, Herschel, GTC, etc) and on an extensive and detailed analysis of these observations (e.g. using radiative transfer codes developed in the group).
