Carbonates and ices in the galaxy-absorber towards PKS 1830-211 and within star-forming regions of the Milky Way
Janet E. Bowey
A pair of 6.0 and 6.9 m absorption features are frequently observed in Milky-Way (MW) molecular-clouds and YSOs; they also occur in the rest-frame of a molecule-rich s…
Sakurai's Object revisited: new laboratory data for carbonates and melilites suggest the carrier of 6.9 m excess absorption is a carbonate
J. E. Bowey, A. M. Hofmeister
We present new room-temperature 1100 - 1800 cm^{-1} spectra of melilite silicates and 600 - 2000 cm^{-1} spectra of three randomly orientated fine-grained carbonates to determine t…
Dust changes in Sakurai's Object: new PAHs and SiC with coagulation of submicron-sized silicate dust into 10 micron-sized melilite grains
Janet E. Bowey
6-14 micron Spitzer spectra obtained at 6 epochs between April 2005 and October 2008 are used to determine temporal changes in dust features associated with Sakurai's Object (V4334…
Infrared Spectra of Pyroxenes (Crystalline Chain Silicates) at Room Temperature
J. E. Bowey, A. M. Hofmeister, E. Keppel
Pyroxene crystals are common in meteorites but few compositions have been recognized in astronomical environments. We present quantitative room-temperature spectra of 17 Mg-- Fe--…
