An outflow origin of the [NeII] emission in the T Tau triplet
R. van Boekel, M. Guedel, Th. Henning +2
(Note: this is a shortened version of the original "structured" (A&A format) abstract.) The 12.81 micrometer [NeII] line has recently gained interest as a potential tracer of gas i…
Lack of PAH emission toward low-mass embedded young stellar objects
V. C. Geers, E. F. van Dishoeck, K. M. Pontoppidan +4
PAHs have been detected toward molecular clouds and some young stars with disks, but have not yet been associated with embedded young stars. We present a sensitive mid-IR spectrosc…
An X-ray photometry system I: Chandra ACIS
H. -J. Grimm, J. McDowell, G. Fabbiano +1
We present a system of X-ray photometry for the Chandra satellite. X-ray photometry can be a powerful tool to obtain flux estimates, hardness ratios, and colors unbiased by assumpt…
The characteristics of the IR emission features in the spectra of Herbig Ae stars: Evidence for chemical evolution
C. Boersma, J. Bouwman, F. Lahuis +4
Herbig Ae/Be stars are a class of young pre-main sequence stellar objects of intermediate mass and are known to have varying amounts of natal cloud material still present in their…
H2O and OH gas in the terrestrial planet-forming zones of protoplanetary disks
C. Salyk, K. M. Pontoppidan, G. A. Blake +3
We present detections of numerous 10-20 micron H2O emission lines from two protoplanetary disks around the T Tauri stars AS 205A and DR Tau, obtained using the InfraRed Spectrograp…
The c2d Spitzer spectroscopic survey of ices around low-mass young stellar objects II: CO2
Klaus M. Pontoppidan, A. C. A. Boogert, Helen J. Fraser +6
This paper presents Spitzer-IRS spectroscopy of the CO2 15.2 micron bending mode toward a sample of 50 embedded low-mass stars in nearby star-forming clouds, taken mostly from the…
