    Discovery of a massive equatorial torus in the η Carinae stellar system

    The enigmatic object η Carinae is believed to represent an important, but short-lived, unstable phase in the life of the most massive stars, occurring shortly before they explode as supernovae or collapse dire...

    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...

    Dust in LBV Nebulae

    The upper part of the HR diagram is populated by massive, luminous stars that show strong stellar winds. These stellar winds have a profound effect on the evolution of the most massive stars, e.g. they lead to...

    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...

    ISOCAM Imaging of LBVS

    In this poster paper we present ISOCAM1 imaging of the well known LBV AG Car and the candidate LBV G79.29+0.46. AG Car has been extensively studied in the ultraviolet, optical and infrared. The optical nebula aro...
