Probing the mass loss of nearby evolved stars at high angular resolution

Séminaire IPAG de Miguel Montarges (IRAM), jeudi 19 janvier 2017 à 11h00, IRAM seminar room

Evolved stars are the main contributors to the chemical enrichment of the interstellar medium. Nuclear fusion creates heavy elements in their core that are transported up to the photosphere where they are expelled through an important mass loss. As material moves away from the star it is cooling and becoming more complex. Several processes behind this mass loss remain poorly understood.

I will review my recent results in observing the photosphere and the close circumstellar environment of evolved stars using high angular resolution infrared facilities and present my current projects involving radio interferometry.
