Red giants are sometimes surrounded by envelopes, the result of the ejection of stellar
matter at a large rate (̇M>10^-7M_⊙/yr) and at a low velocity (10 km/s). In this review the …

▪ Abstract This review emphasizes the mass loss processes that affect the fates of single
stars with initial masses between one and nine solar masses. Just one epoch of mass loss …

We present year-long, near-infrared Hubble Space Telescope (HST) WFC3 observations
used to search for Mira variables in NGC 1559, the host galaxy of the Type Ia supernova (SN …

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) …

Astrometry in the 1960s and 1970s was still entirely ground-based, and all too often seen
(and experienced by very few) as a rather tedious, time-consuming technique that no longer …

Binary interactions dominate the evolution of massive stars, but their role is less clear for low-
and intermediate-mass stars. The evolution of a spherical wind from an asymptotic giant …

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 …

Context. The third Gaia Data Release covers 34 months of data and includes the second
Gaia catalogue of long-period variables (LPVs), with G variability amplitudes larger than 0.1 …

We present an up-to-date compilation of published Hubble constant (H 0) measurements
that are independent of the cosmic microwave background sound horizon scale. This …

We present a detailed study of the viewing angles of the LMC disk plane. We find that our
viewing direction differs considerably from the commonly accepted values, which has …
