The crystalline fraction of interstellar silicates in starburst galaxies
F. Kemper, A. J. Markwick, Paul M. Woods
We present a model using the evolution of the stellar population in a starburst galaxy to predict the crystallinity of the silicates in the interstellar medium of this galaxy. We t…
Rusty old stars: a source of the missing interstellar iron?
Iain McDonald, Gregory C. Sloan, Albert A. Zijlstra +5
Iron, the Universe's most abundant refractory element, is highly depleted in both circumstellar and interstellar environments, meaning it exists in solid form. The nature of this s…
The abundance of HNCO and its use as a diagnostic of environment
D. M. Tideswell, G. A. Fuller, T. J. Millar +1
We aim to investigate the chemistry and gas phase abundance of HNCO and the variation of the HNCO/CS abundance ratio as a diagnostic of the physics and chemistry in regions of mass…
Three-micron spectra of AGB stars and supergiants in nearby galaxies
M. Matsuura, A. A. Zijlstra, J. Th. van Loon +7
The dependence of stellar molecular bands on the metallicity is studied using infrared L-band spectra of AGB stars (both carbon-rich and oxygen-rich) and M-type supergiants in the…
Period and chemical evolution of SC stars
Albert A. Zijlstra, T. R. Bedding, Andrew J. Markwick +8
The SC and CS stars are thermal-pulsing AGB stars with C/O ratio close to unity. Within this small group, the Mira variable BH Cru recently evolved from spectral type SC (showing Z…
