Title: Evolution of Classical Novae Dust Shells
Abstract:
From our early observations of stars to our observations of the
early universe we have found dust, making an understanding of dust
fundamental to astronomy. Novae provide a laboratory to observe dust
processes on a convenient human time-scale. However, current dust
masses derived from observations are much larger than theoretical models
predict. These models assume a homogeneous shell for computational
simplicity. In contrast we will use an advanced radiative transfer dust
code capable of modeling small filling factors. We request 2 nights on
the SOAR 4.1m and 4 nights on the SMARTS 0.9m to survey old dusty novae
in optical and infrared in conjunction with the WISE satellite survey.
We aim to track the formation and evolution of dust shells from both old
and recent novae.
