Sensitivity of PDR Calculations to Microphysical Details
N. P. Abel, P. A. M. van Hoof, G. Shaw +2
Our understanding of physical processes in Photodissociation regions or Photon Dominated Regions (PDRs) largely depends on the ability of spectral synthesis codes to reproduce the…
Kinematics and H_2 morphology of the multipolar Post-AGB star IRAS 16594-4656
G. C. Van de Steene, T. Ueta, P. A. M. van Hoof +2
context: The spectrum of IRAS 16594-4656 shows shock excited H_2 emission and collisionally excited emission lines such as[O I],[C I],and [Fe II]. aim: The goal is to determine the…
On the enhanced cosmic-ray ionization rate in the diffuse cloud towards Zeta Persei
Gargi Shaw, G. J. Ferland, R. Srianand +3
The spatial distribution of the cosmic-ray flux is important in understanding the Interstellar Medium (ISM) of the Galaxy. This distribution can be analyzed by studying different m…
The onset of photoionization in Sakurai's Object (V4334 Sgr)
P. A. M. van Hoof, M. Hajduk, Albert A. Zijlstra +6
We investigate the reheating of the very late thermal pulse (VLTP) object V4334 Sgr (Sakurai's Object) using radio observations from the Very Large Array, and optical spectra obtai…
IRAS08281-4850 and IRAS14325-6428: two A-type post-AGB stars with s-process enrichment
M. Reyniers, G. C. Van de Steene, P. A. M. van Hoof +1
One of the puzzling findings in the study of the chemical evolution of (post-)AGB stars is why very similar stars (in terms of metallicity, spectral type, infrared properties, etc.…
The Post-Agb Star IRAS 16594-4656
Griet C. Van de Steene, Peter A. M. van Hoof
We present the basic properties of the multipolar post-AGB star IRAS 16594-4656, and discuss in particular its near infrared spectrum which shows shock excited H2 and [Fe II] emiss…
