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.
