Searching for Gas-Rich Disks around T Tauri Stars in Lupus
T. A. van Kempen, E. F. van Dishoeck, C. Brinch +1
AIMS : To characterize the molecular environment of classical T Tauri stars in Lupus observed with the Spitzer Space Telescope and to search for gas-rich disks toward these sources…
Warm Molecular Gas in the Outflow and Envelope of IRAS 12496-7650 (DK Cha)
T. A. van Kempen, M. R. Hogerheijde, E. F. van Dishoeck +3
Aims:To obtain insight into the physical structure of the warm gas in the inner envelope of protostars and the interaction with the outflow. Methods: Sub-millimeter observations of…
Astrochemical confirmation of the rapid evolution of massive YSOs and explanation for the inferred ages of hot cores
S. D. Doty, E. F. van Dishoeck, J. C. Tan
Aims. To understand the roles of infall and protostellar evolution on the envelopes of massive young stellar objects (YSOs). Methods. The chemical evolution of gas and dust is trac…
Water destruction by X-rays in young stellar objects
P. Stauber, J. K. Jorgensen, E. F. van Dishoeck +2
We study the H2O chemistry in star-forming environments under the influence of a central X-ray source and a central far ultraviolet (FUV) radiation field. The gas-phase water chemi…
Desorption rates and sticking coefficients for CO and N2 interstellar ices
S. E. Bisschop, H. J. Fraser, K. I. Oberg +2
We present Temperature Programmed Desorption (TPD) experiments of CO and N2 ices in pure, layered and mixed morphologies at various ice "thicknesses" and abundance ratios as well a…
