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…
A PDR-Code Comparison Study
M. Roellig, N. P. Abel, T. Bell +21
We present a comparison between independent computer codes, modeling the physics and chemistry of interstellar photon dominated regions (PDRs). Our goal was to understand the mutua…
Chemistry and line emission from evolving Herbig Ae disks
B. Jonkheid, C. P. Dullemond, M. R. Hogerheijde +1
Aims: To calculate chemistry and gas temperature of evolving protoplanetary disks with decreasing mass or dust settling, and to explore the sensitivity of gas-phase tracers. Method…
Modeling the gas-phase chemistry of the transitional disk around HD 141569A
B. Jonkheid, I. Kamp, J. -C. Augereau +1
Aims: The chemistry, distribution and mass of the gas in the transitional disk around the 5 Myr old B9.5 V star HD 141569A are constrained. Methods: A quasi 2-dimensional (2D) chem…
The gas temperature in flaring disks around pre-main sequence stars
B. Jonkheid, F. G. A. Faas, G. -J. van Zadelhoff +1
A model is presented which calculates the gas temperature and chemistry in the surface layers of flaring circumstellar disks using a code developed for photon-dominated regions. Sp…
