Local kinematics of K and M giants from CORAVEL/Hipparcos/Tycho-2 data: Revisiting the concept of superclusters
The availability of the Hipparcos Catalogue has triggered many kinematic and dynamical studies of the solar neighbourhood. Nevertheless, those studies generally lacked the third component of the…

HERMES: a high-resolution fibre-fed spectrograph for the Mercator telescope
The HERMES high-resolution spectrograph project aims at exploiting the specific potential of small but flexible telescopes in observational astrophysics. The optimised optical design of the…

Multiple Molecular Winds in Evolved Stars. I. A Survey of CO(2-1) and CO(3-2) Emission from 45 Nearby Asymptotic Giant Branch Stars
This paper describes observations of a new phenomenon in evolved mass-losing asymptotic giant branch (AGB) stars: the presence of two winds with different expansion velocities. CO(2-1) and CO(3-2)…

Reprocessing the Hipparcos data of evolved stars - III. Revised Hipparcos period–luminosity relationship for galactic long-period variable stars
We analyze the K band luminosities of a sample of galactic long-period variables using parallaxes measured by the Hipparcos mission. The parallaxes are in most cases re-computed from the Hipparcos…

More lead stars
The standard model for the operation of the s-process in asymptotic giant branch (AGB) stars predicts that low-metallicity ([Fe/H] ≲ -1) AGB stars should exhibit large overabundances of Pb and Bi as…

CS 30322-023: an ultra metal-poor TP-AGB star?
Context. The remarkable properties of CS 30322-023 became apparent during the course of a high-resolution spectroscopic study of a sample of 23 carbon-enhanced, metal-poor (CEMP) stars. Aims. This…

The Gaia-ESO Public Spectroscopic Survey
The Gaia-ESO Public Spectroscopic Survey has begun and will obtain high quality spectroscopy of some 100000 Milky Way stars, in the field and in open clusters, down to magnitude 19, systematically ...
A far-infrared survey of bow shocks and detached shells around AGB stars and red supergiants
Far-infrared Herschel/PACS images at 70 and 160 micron of a sample of 78 Galactic evolved stars are used to study the (dust) emission structures, originating from stellar wind-ISM interaction. In…

Discovery of three lead-rich stars
TLDR
Analysis shows that three metal-poor stars are more enriched in lead than in any other element heavier than iron, and excellent agreement between the observed and predicted abundances reinforces current understanding of the detailed operation of the s-process deep in the interiors of AGB stars.

Re-processing the Hipparcos Transit Data and intermediate astrometric data of spectroscopic binaries: I. Ba, CH and Tc-poor S stars
Only 235 entries were processed as astrometric binaries with orbits in the Hipparcos and Tycho Catalogue (ESA 1997). However, the Intermediate Astrometric Data (IAD) and Transit Data (TD) made…
