Spatially extended PAHs in circumstellar disks around T Tauri and Herbig Ae stars
V. C. Geers, E. F. van Dishoeck, R. Visser +4
Our aim is to determine the presence and location of the emission from polycyclic aromatic hydrocarbons (PAHs) towards low and intermediate mass young stars with disks using large…
Cold Disks: Spitzer Spectroscopy of Disks around Young Stars with Large Gaps
J. M. Brown, G. A. Blake, C. P. Dullemond +10
We have identified four circumstellar disks with a deficit of dust emission from their inner 15-50 AU. All four stars have F-G spectral type, and were uncovered as part of the Spit…
Spatial separation of small and large grains in the transitional disk around the young star IRS 48
V. C. Geers, K. M. Pontoppidan, E. F. van Dishoeck +5
We present spatially resolved mid-infrared images of the disk surrounding the young star IRS 48 in the Ophiuchus cloud complex. The disk exhibits a ring-like structure at 18.7 micr…
Abundant crystalline silicates in the disk of a very low mass star
B. Merin, J. -C. Augereau, E. F. van Dishoeck +16
We announce the discovery of SST-Lup3-1, a very low mass star close to the brown dwarf boundary in Lupus III with a circum(sub)stellar disk, discovered by the `Cores to Disks' Spit…
PAH chemistry and IR emission from circumstellar disks
R. Visser, V. C. Geers, C. P. Dullemond +3
Aims. The chemistry of, and infrared (IR) emission from, polycyclic aromatic hydrocarbons (PAHs) in disks around Herbig Ae/Be and T Tauri stars are investigated. The equilibrium di…
