TL;DR: The Long-Wavelength Spectrometer (LWS) is one of two complementary spectrometers aboard the European Space Agency's Infrared Space Observatory (ISO) (Kessler et al., 1996) as mentioned in this paper.
Book ChapterDOI
Dusty LBV Nebulae: Tracing the Mass Loss History of the Most Massive Stars
L.B.F.M. Waters,R.H.M. Voors,Patrick W. Morris,Norman R. Trams,Alex de Koter,Henny J. G. L. M. Lamers +5 more
TL;DR: In this paper, spectra obtained with the Infared Space Observatory (ISO) of the dust shells surrounding several Luminous Blue Variables (LBVs), both in our galaxy and in the LMC, are presented.
Journal Article
HD 52961 : an extremely metal-deficient, CNO- and S-rich, pulsating star embedded in a dust cloud
TL;DR: In this paper, it was found that the iron abundance of HD 52961 may be as low as [Fe/H] = −4.8; the abundances of carbon, nitrogen, oxygen, and also sulphur are enhanced with respect to iron by several orders of magnitude.
Journal Article
