This book deals with stars during a short episode before they undergo a ma jor, and fatal,
transition. Soon the star will stop releasing nudear energy, it will become a planetary nebula …

The central kpc of the Milky Way might be expected to differ significantly from the rest of the
Galaxy with regard to gasdynamics and the formation of young stellar objects (YSOs). We …

Near-and mid-IR survey data from DENIS and ISOGAL are used to investigate the structure
and formation history of the inner 10°(1.4 kpc) of the Milky Way galaxy. Synthetic bolometric …

Abstract We present a Spitzer Space Telescope spectroscopic survey of mass-losing carbon
stars (and one oxygen-rich star) in the Large Magellanic Cloud (LMC). The stars represent …

The ISOGAL project is an infrared survey of specific regions sampling the Galactic Plane
selected to provide information on Galactic structure, stellar populations, stellar mass-loss …

The Galactic center region, including the nuclear disk, has until recently been largely
avoided in chemical census studies because of extreme extinction and stellar crowding …

We present 86 GHz () SiO maser line observations with the IRAM 30-m telescope of a
sample of 441 late-type stars in the Inner Galaxy (). These stars were selected on the basis …

Context. Mass-loss from evolved stars chemically enriches the interstellar medium (ISM).
Stellar winds from massive stars and their explosions as supernovae shape the ISM and …

Young massive star clusters, like the six red supergiant clusters in the Scutum complex,
provide valuable insights into star formation and galaxy structures. We investigated the high …

The 7 and 15 μm observations of selected fields in the Galactic Plane obtained with ISOCAM
during the ISOGAL program offer a unique possibility to search for previously unknown …
