Sun-bathing around low-mass protostars: APEX-CHAMP+ observations of high-J CO
Ewine F. van Dishoeck, Tim A. van Kempen, Rolf Guesten
We present the first maps of high-excitation CO J=6-5 and 7-6 and isotopologue lines over 2'-5' regions at 10" resolution toward low-mass protostars to probe the origin of the warm…
The nature of the Class I population in Ophiuchus as revealed through gas and dust mapping
T. A. van Kempen, E. F. van Dishoeck, D. M. Salter +3
The Ophiuchus clouds, in particular L~1688, are an excellent region to study the embedded phases of star formation, due to the relatively large number of protostars. However, the s…
Modeling water emission from low-mass protostellar envelopes
T. A. van Kempen, S. D. Doty, E. F. van Dishoeck +2
Within low-mass star formation, water vapor plays a key role in the chemistry and energy balance of the circumstellar material. The Herschel Space Observatory will open up the poss…
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…
