Circumstellar Carbonaceous Material Associated with Late-Type Dusty WC Wolf-Rayet Stars
Published online by Cambridge University Press: 19 September 2017
Abstract
Our own solar system and other planetary systems are composed of organic dust created in the outflows in dying stars. Here, we examine an unlikely source of carbonaceous material in interstellar space, the harsh environment of Wolf-Rayet (WR) stars. We have used spectroscopic data from the Short Wavelength Spectrometer on the Infrared Space Observatory to examine infrared emission and absorption features in the 6 to 9 μm spectral region of hot massive WC-type WR stars. We conclude that these features are due to amorphous carbon dust in their circumstellar environment.
