The influence of Hinode/SOT NFI instrumental effects on the visibility of simulated prominence fine structures in H alpha

Popis výsledku v původním jazyce

In the present work, we investigate how synthetic H alpha images of simulated prominences are impacted by the instrumental effects induced by the Narrowband Filter Imager (NFI) of the Solar Optical Telescope (SOT) onboard the Hinode satellite. . The comparison between the SOT-like synthetic H alpha images and the synthetic H alpha line-center images shows that all large and small-scale features are very similar in both visualizations and that the same very faint prominence fine structures can be discerned in both. This demonstrates that the computationally efficient H alpha line-center visualization technique can be reliably used for the purpose of visualization of complex 3D prominence models. In addition, the qualitative comparison between the SOT-like synthetic images and prominence observations shows that the 3D WPFS models can reproduce large-scale prominence features rather well. However, the distribution of the prominence fine structures is significantly more diffuse in the observations than in the models and the diffuse intensity areas surrounding the observed prominences are also not present in the synthetic images. We also found that the maximum intensities reached in the models are about twice as high as those present in the observations-an indication that the mass-loading assumed in the present 3D WPFS models might be too large.
