Physics

Scientific paper

We will use IRAC mapping (along with MIPS images and IRS spectra) to study the stellar ejecta primarily in planetary nebulae. IRAC will map the distribution of emission from PAHs, thermal emission from dust, along with numerous atomic and molecular features from photon-dominated and shock-heated gas. These images will show the structure of the nebular shells and cool halos which will provide insight on the formation and evolution of the planetary nebulae and the ejected matter as well as information on the mass loss of the central stars.
