The peculiar dust shell of Nova DZ Cru (2003)

Abstract: We present Spitzer Space Telescope observations of the "peculiar variable" DZ Cru, identified by Rushton et al. (2008, MNRAS, 386, 289) as a classical nova. A dust shell, on which are superimposed a number of features, is prominent in the 5-35micron range some 4 years after eruption. We suggest that the dust in DZ Cru is primarily hydrogenated amorphous carbon in which aliphatic bands currently predominate, and which may either become predominantly aromatic as the dust is photo-processed by ultraviolet radiati… Show more

“…Sloan et al (2007) suggested that the carri-ers of the Class C UIR spectra can be a mixture of aromatic and aliphatic materials including more fragile aliphatic bonds that have not yet been exposed to intense UV radiation because aliphatic structures are expected to be broken in such harsh environments. Evans et al (2010) proposed that the UIR spectra in a dusty classical nova, DZ Cru, may be attributed to species in which aliphatic bonds predominate rather than PAH molecules. They also suggested that the carriers including fragile aliphatic structures have been protected in a dense clump and have only recently been exposed to the harsh condition.…”
