Planetary Nebulae: Exposing the Top Polluters of the ISM
Joseph L. Hora, Massimo Marengo, Howard A. Smith +2
The high mass loss rates of stars in their asymptotic giant branch (AGB) stage of evolution is one of the most important pathways for mass return from stars to the ISM. In the plan…

An IR view of mass loss in Long Period Variables
Massimo Marengo, Margarita Karovska, Zeljko Ivezic
We have investigated the mass loss processes in Long Period Variables, by combining radiative transfer modeling with mid-IR imaging and spectroscopic observations. We find a correl…

Mid-infrared imaging of AGB star envelopes. II. Modelling of observed sources
M. Marengo, G. Canil, G. Silvestro +3
Radiative transfer modelling of AGB circumstellar envelopes is applied to a sample of AGB stars previously observed with the mid-IR imaging camera TIRCAM (Busso et al. 1996: Paper…
