Photodesorption of Ices II: H2O and D2O
Karin I. Oberg, Harold Linnartz, Ruud Visser +1
Gaseous H2O has been detected in several cold astrophysical environments, where the observed abundances cannot be explained by thermal desorption of H2O ice or by H2O gas phase for…
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…
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…
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…
