As low-and intermediate-mass stars reach the asymptotic giant branch (AGB), they have
developed into intriguing and complex objects that are major players in the cosmic gas/dust …

Context. The post-asymptotic giant branch (AGB) phase is arguably one of the least
understood phases of the evolution of low-and intermediate-mass stars. The two grids of …

We present a large set of theoretical isochrones, whose distinctive features mostly reside on
the greatly-improved treatment of the thermally-pulsing asymptotic giant branch (TP-AGB) …

Dust is a ubiquitous feature of the cosmos, impinging directly or indirectly on most fields of
modern astronomy and astrophysics. Dust in the Galactic Environment, Second Edition …

We present new synthetic models of the TP-AGB evolution. They are computed for 7 values
of initial metal content (Z from 0.0001 to 0.03) and for initial masses between 0.5 and 5.0 …

The composition of the dust mixture and the amounts of dust returned into the interstellar
medium during the evolution of low and intermediate mass stars on the AGB is calculated by …

Chemical equilibrium has proven extremely useful for predicting the chemical composition of
AGB atmospheres. Here we use a recently developed code and an updated thermochemical …

We have studied the CO emission from protoplanetary nebulae (PPNe). Our sample is
composed of 37 objects and includes, we think, all well identified PPNe detected in CO …

The large amounts of dust detected in sub-millimeter galaxies and quasars at high redshift
pose a challenge to galaxy formation models and theories of cosmic dust formation. At z> 6 …

We report on an analysis of the gas and dust budget in the interstellar medium (ISM) of the
Large Magellanic Cloud (LMC). Recent observations from the Spitzer Space Telescope …
