| Abstract: |
Classical novae present a way to study dust formation on convenient human
timescales. There are, however, some issues with current dust modelling
techniques. Some novae are reported to have unusually high dust masses,
within an order of magnitude of the total ejected mass. Model dust shell
SEDs can not always reproduce observed “excess” optical light.
We propose that these issues may be solved by considering non-uniform dust.
This project aims to study dust in CNe shells from formation and evolution to
interaction with the ISM by applying the advanced dust modelling code
DIRTY to OIR photometry. First results for V868 Cen will be presented
and we will describe our ongoing campaign using late-time observations of
old dusty novae to study dust
dissemination in the ISM. |
