Grupo de Estrellas Evolucionadas

Utilizamos observaciones a multifrecuencias, modelos teóricos y simulaciones numéricas para estudiar los diversos fenómenos asociados a las etapas finales de las estrellas. Nuestros estudios abarcan las estrellas AGB y supergigantes rojas, las nebulosas planetarias y nebulosas Wolf-Rayet, las novas y remanentes de supernova, tanto en nuestra Galaxia como en galaxias externas.
