Ionization fronts and their interaction with density fluctuations: implications for reionization
Ilian T. Iliev, Paul R. Shapiro, Evan Scannapieco +4
The propagation of cosmological ionization fronts (I-fronts) during reionization is strongly influenced by small-scale structure. Here we summarize our recent attemps to understand…
Three-Dimensional Adaptive Mesh Refinement Simulations of Point-Symmetric Nebulae
Erik-Jan Rijkhorst, Vincent Icke, Garrelt Mellema
Previous analytical and numerical work shows that the generalized interacting stellar winds model can explain the observed bipolar shapes of planetary nebulae very well. However, m…
3D AMR Simulations of Point-Symmetric Nebulae
Erik-Jan Rijkhorst, Vincent Icke, Garrelt Mellema
At the end of their lives low mass stars such as our Sun lose most of their mass. The resulting planetary nebulae show a wide variety of shapes, from spherical to highly bipolar. A…
The electron temperature of the inner halo of the Planetary Nebula NGC 6543
Siek Hyung, Garrelt Mellema, Seong-Jae Lee +1
We investigate the electron temperature of the inner halo and nebular core regions of NGC 6543, using archival Hubble Space Telescope (HST) Wide Field Planetary Camera 2 (WFPC2) im…
Shaping Planetary Nebulae: is it different for [WR] stars?
Garrelt Mellema
This review discusses the physics of the formation of planetary nebulae around low mass WR stars, or [WR] stars. It especially focuses on the differences which can be expected due…
Radiative Feedback and the Photoevaporation of Intergalactic Clouds
Paul R. Shapiro, Alejandro C. Raga, Garrelt Mellema
The first sources of ionizing radiation to condense out of the dark and neutral IGM sent ionization fronts sweeping outward through their surroundings, overtaking other primordial…
