Eta Car through the eyes of interferometers

Olivier Chesneau, R. Van Boekel, T. Herbst +6

The core of the nebula surrounding Eta Carinae has recently been observed with VLT/NACO, VLTI/VINCI, VLTI/MIDI and VLTI/AMBER in order to spatially and spectrally constrain the war…

Hydrogen infrared recombination lines as diagnostic tool for hot star wind geometry

A. Lenorzer, A. de Koter, L. B. F. M. Waters

We have analysed the infrared hydrogen recombination lines of a sample of well studied hot massive stars observed with the Infrared Space Observatory. Our sample contains stars fro…

ISO spectroscopy of circumstellar dust in the Herbig Ae systems AB Aur and HD 163296

M. E. van den Ancker, J. Bouwman, P. R. Wesselius +3

Using both the Short- and Long-wavelength Spectrometers on board the Infrared Space Observatory (ISO), we have obtained infrared spectra of the Herbig Ae systems AB Aur and HD 1632…

The infrared spectrum of the Be star gamma Cassiopeiae

S. Hony, L. B. F. M. Waters, P. A. Zaal +6

We present the 2.4-45 micrometer ISO-SWS spectrum of the Be star gamma Cas (B0.5 IVe). The spectrum is characterised by a thermal continuum which can be well fit by a power-law S_n…

2.4 - 197 micron spectroscopy of OH/IR stars: The IR characteristics of circumstellar dust in O-rich environments

R. J. Sylvester, F. Kemper, M. J. Barlow +4

Infrared spectra of a number of evolved O-rich stars have been obtained with the Short- and Long- Wavelength spectrometers on board the Infrared Space Observatory. The very broad w…

ISO observations of obscured Asymptotic Giant Branch stars in the Large Magellanic Cloud

Norman R. Trams, Jacco Th. van Loon, L. B. F. M. Waters +8

We present ISO photometric and spectroscopic observations of a sample of 57 bright Asymptotic Giant Branch stars and red supergiants in the Large Magellanic Cloud, selected on the…
