Probing Protoplanetary Disks with Silicate Emission: Where is the silicate emission zone?
J. E. Kessler-Silacci, C. P. Dullemond, J. -C. Augereau +6
Recent results indicate that the grain size and crystallinity inferred from observations of silicate features may be correlated with spectral type of the central star and/or disk g…
Modeling Spitzer observations of VV Ser. II. an extended quantum heated nebula and a disk shadow
Klaus M. Pontoppidan, Cornelis P. Dullemond, Geoffrey A. Blake +4
We present mid-infrared Spitzer IRAC and MIPS images of the UX Orionis star VV Ser and the surrounding cloud. The 5.6--70 micron images show bright, localized and nebulous emission…
Spitzer-IRS spectra of disks around T Tauri stars II. PAH emission features
V. C. Geers, J. -C. Augereau, K. M. Pontoppidan +10
Aims: We search for PAH features towards T Tauri stars and compare them with surveys of Herbig Ae/Be stars. The presence and strength of the PAH features are interpreted with disk…
