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…
