APEX-SEPIA660 Early Science: Gas at densities above cm towards OMC-1
A. Hacar, M. R. Hogerheijde, D. Harsono +12
Context. The star formation rates and stellar densities found in young massive clusters suggest that these stellar systems originate from gas at densities n(H) cm$^{-3}…
Performance studies of the CMS Strip Tracker before installation
CMS Tracker Collaboration
In March 2007 the assembly of the Silicon Strip Tracker was completed at the Tracker Integration Facility at CERN. Nearly 15% of the detector was instrumented using cables, fiber o…
Probing the Early Stages of Low-Mass Star Formation in LDN 1689N: Dust and Water in IRAS 16293-2422A, B, and E
Ronald Stark, Goeran Sandell, Sara C. Beck +8
We present deep images of dust continuum emission at 450, 800, and 850 micron of the dark cloud LDN 1689N which harbors the low-mass young stellar objects (YSOs) IRAS 16293-2422A a…
Mass loss and rotational CO emission from Asymptotic Giant Branch stars
F. Kemper, R. Stark, K. Justtanont +5
We present submillimeter observations of rotational transitions of carbon monoxide from J = 2 -> 1 up to 7 -> 6 for a sample of Asymptotic Giant Branch stars and red supergiants. I…
Line emission from circumstellar disks around A stars
Inga Kamp, Gerd-Jan van Zadelhoff, Ewine van Dishoeck +1
The nature of the tenuous disks around A stars has raised considerable controversy in the literature during the past decade. The debate whether or not the disk around beta Pictoris…
Highly abundant HCN in the inner hot envelope of GL 2591: probing the birth of a hot core?
A. M. S. Boonman, R. Stark, F. F. S. van der Tak +5
We present observations of the v2=0 and vibrationally excited v2=1 J=9-8 rotational lines of HCN at 797 GHz toward the deeply embedded massive young stellar object GL 2591, which p…
