Large grains in disks around young stars: ATCA observations of WW Cha, RU Lup, and CS Cha
Dave Lommen, Sarah Maddison, Chris Wright +3
Grains in disks around young stars grow from interstellar submicron sizes to planetesimals over the course of several Myr. Thermal emission of large grains or pebbles can be best o…
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…
Photoprocesses in protoplanetary disks
E. F. van Dishoeck, B. Jonkheid, M. C. van Hemert
Circumstellar disks are exposed to intense ultraviolet radiation from the young star. In the inner disks, the UV radiation can be enhanced by more than seven orders of magnitude co…
Photodissociation of small carbonaceous molecules of astrophysical interest
M. C. van Hemert, E. F. van Dishoeck
Astronomical observations have shown that small carbonaceous molecules can persist in interstellar clouds exposed to intense ultraviolet radiation. Current astrochemical models lac…
Band profiles and band strengths in mixed H2O:CO ices
Jordy Bouwman, Wiebke Ludwig, Zainab Awad +4
A laboratory study on the band profiles and band strengths of H2O in CO ice, and vice versa, is presented and interpreted in terms of two models. The results show that a mutual int…
The Spitzer c2d Survey of Nearby Dense Cores: IV. Revealing the Embedded Cluster in B59
Timothy Y. Brooke, Tracy L. Huard, Tyler L. Bourke +22
Infrared images of the dark cloud core B59 were obtained with the Spitzer Space Telescope as part of the "Cores to Disks" Legacy Science project. Photometry from 3.6-70 microns ind…
