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. I. The circumstellar disk of a UX Orionis star
Klaus M. Pontoppidan, Cornelis P. Dullemond, Geoffrey A. Blake +5
We present mid-infrared Spitzer-IRS spectra of the well-known UX Orionis star VV Ser. We combine the Spitzer data with interferometric and spectroscopic data from the literature co…
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…
Young, Low-Mass Brown Dwarfs with Mid-Infrared Excesses
K. N. Allers, J. E. Kessler-Silacci, L. A. Cieza +1
We have combined new I, J, H, and Ks imaging of portions of the Chamaeleon II, Lupus I, and Ophiuchus star-forming clouds with 3.6 to 24 micron imaging from the Spitzer Legacy Prog…
