On the origin of [NeII] 12.81 micron emission from pre-main sequence stars: Disks, jets, and accretion
M. Guedel, F. Lahuis, K. R. Briggs +6
(Abridged) We have conducted a study of [NeII] line emission based on a sample of 92 pre-main sequence stars mostly belonging to the infrared Class II, including 13 accreting trans…
A Spitzer survey of mid-infrared molecular emission from protoplanetary disks I: Detection rates
Klaus M. Pontoppidan, Colette Salyk, Geoffrey A. Blake +3
We present a Spitzer InfraRed Spectrometer search for 10-36 micron molecular emission from a large sample of protoplanetary disks, including lines from H2O, OH, C2H2, HCN and CO2.…
First results of the Herschel Key Program 'Dust, Ice and Gas in Time': Dust and Gas Spectroscopy of HD 100546
B. Sturm, J. Bouwman, Th. Henning +40
We present far-infrared spectroscopic observations, taken with the Photodetector Array Camera and Spectrometer (PACS) on the Herschel Space Observatory, of the protoplanetary disk…
Dust, Ice and Gas in Time (DIGIT) Herschel program first results: A full PACS-SED scan of the gas line emission in protostar DK Cha
T. A. van Kempen, J. D. Green, N. J. Evans +42
DK Cha is an intermediate-mass star in transition from an embedded configuration to a star plus disk stage. We aim to study the composition and energetics of the circumstellar mate…
Spitzer Spectroscopy of the Transition Object TW Hya
Joan R. Najita, John S. Carr, Stephen E. Strom +5
We report sensitive Spitzer IRS spectroscopy in the 10-20 micron region of TW Hya, a nearby T Tauri star. The unusual spectral energy distribution of the source, that of a transiti…
