Forward Modeling of Active Region Coronal Emissions: II. Implications for Coronal Heating
In Paper I, we introduced and tested a method for predicting solar active region coronal emissions using magnetic field measurements and a chosen heating relationship. Here, we apply this forward-modeling technique to 10 active regions observed with the Mees Solar Observatory Imaging Vector Magnetograph and the Yohkoh Soft X-ray Telescope. We produce synthetic images of each region using four p...

متن کاملOn the origin of the fast solar wind in polar coronal funnels
Funnels are open magnetic structures connecting the chromosphere with the solar corona (Axford & McKenzie 1997; Marsch & Tu 1997; Hackenberg et al. 1999). We investigate the stationary plasma flow out of funnels with a flux-tube model. The funnel area function is derived from an analytical 2-D magnetic field model. Since the funnel height is only approximately 15 Mm, the area function for great...
متن کاملForward Modeling of EUV and Gyrosynchrotron Emission from Coronal Plasmas with FoMo
The FOMO code was developed to calculate the EUV and UV emission from optically thin coronal plasmas. The input data for FOMO consists of the plasma density, temperature and velocity on a 3D grid. This is translated to emissivity on the 3D grid, using CHIANTI data. Then, the emissivity is integrated along the line-of-sight (LOS) to calculate the emergent spectral line for synthetic spectrometer...
متن کاملForward modeling of the coronal response to reconnection in an X-ray bright point
We present a novel gasdynamic model of the corona and transition region confined by a static flux tube. Our model allows completely general specification of an asymmetric flux tube geometry, so that detailed comparison with observations can be made. Nonlocal effects such as opacity and ambipolar diffusion are important to the transition region; it is shown that these effects can be modeled loca...
