Door middel van gedetailleerde studies aan de infrarood gegevens van oude sterren is het stof rond koolstofrijke Rode Reuzen onderzocht. De aanwezigheid van een aantal nieuwe materialen in de ruimte is ontdekt. Daarmee is een completer beeld van de samenstelling, locatie en het lot van het stof rond koolstofrijke oude sterren verkregen. Daarmee verschaffen de in dit proefschrift gepresenteerde studies een rijker inzicht in het stof rond oude sterren en deze sterren zelf.

The underlying astrophysical mechanisms of the objects known as asymptotic giant branch stars - the structures that occur during the dramatic period prior to a star's death - is the main theme of this text. Over the past three decades, asymptotic giant branch stars have become a topic of their own, and the contributions to this volume all focus on these entities themselves, rather than their connections to other fields of astronomy. Among the many topics covered are new methods of high- quality infrared observation and the more detailed and realistic simulations made possible by increasingly fast computers. This collection should be useful to graduate students who work in the field, teachers who want to address the subject in their courses, and to astronomers from various backgrounds who are interested in the astrophysics of AGB stars.

Analysis of the IRAS low resolution spectra show that the 8-22 micron spectral range show a variety of emission features. The strongest features in spectra of M stars are the 10 and 18 micron silicate emission features. In addition a three-component feature with peaks at 10, 11 and 13.1 micron and a weak, broad 9-15 micron feature is present in many M variable stars. Most carbon stars show the 11.2 micron SiC emission feature as well as, in some cases, an unidentified 8-9 micron emission feature. The MS, S and SC stars show a range of emission features whose peaks range from 10 to 11.2 micron. The excess emission above the underlying photospheric continuum in the 8-22 micron region for S Mira variables shows a sharp increase for period greater than about 370 days.
