Description

Photometry, together with 2-4 and 8-13 μm spectrometry, of Nova Aquilae 1982, obtained during its dust shell phase is presented. The photometry indicates that if dust formation occurred in the outburst ejecta it did so at an anomalously early stage of the outburst; alternatively the dust shell may have predated the eruption. Spectrometry at the shorter wavelengths suggests the presence of broad, weak features, whilst that in the 8-13 μm window shows strong emission from silicate grains. This indicates that, unlike the situation in previous dusty novae, the grains around Nova Aquilae formed in an oxygen-rich environment. (author)
