    Molecules in the AGB Stars of Nearby Galaxies

    We obtained infrared spectra of Asymptotic Giant Branch (AGB) stars in nearby galaxies, and measured the equivalent widths of HCN and C2H2 bands for the carbon-rich stars, and SiO abundances for the oxygen-rich s...

    Young Stars and Their Circumstellar Disks in the σ Orionis Cluster

    The σ Orionis cluster is a young association evolving under the disruptive influence of its massive O-star namesake. We are analysing this cluster as part of a program to characterise the influence of O-stars ...

    Three Micron Spectra of Carbon Stars in the Large Magellanic Cloud

    Infrared spectra of six carbon-rich stars were obtained with the Very Large Telescope (VLT). We found a metallicity dependence in the equivalent width of the molecular bands, and we discuss the causes of this

    An oxygen-rich dust disk surrounding an evolved star in the Red Rectangle

    The Red Rectangle1 is the prototype of a class of carbon-rich reflection nebulae surrounding low-mass stars in the final stages of evolution. The central star of this nebula has ejected most of its layers (during...

    Evolution and Mass Loss of AGB Stars in the Small Magellanic Cloud

    To study the final stages of the evolution of stars in the range of 1–8M ⊙ we have started a project on AGB stars in the Small Magellanic Cloud (SMC). Based on the IRAS Faint Source Catalog we have ...

    ISO Spectroscopy of AGB Stars in the Magellanic Clouds

    The study of AGB stars in the Magellanic Clouds has an important advantage over the study of galactic objects because of the known distance to the sources. Unfortunately the sources are relatively faint, makin...

    Infrared Observations of High-Mass X-Ray Binaries

    We present the first results of our ISO program on High-Mass X-ray Binaries (HMXBs). Infrared photometry, obtained at different aspect angles of the systems, is used to investigate the massive star’s disrupted...

    ISO’s View on AFGL 4106

    Almost all stars pass through a short phase of extensive mass loss at the end of their life, either as Red Supergiant (RSG), for massive stars, or Asymptotic Giant Branch (AGB) star, for low- and intermediate ...
