Description

This repository provides the high resolution version of the animation corresponding to Figure 2 of the manuscript ''Bifrost models of the Quiet Sun. I. Comparison with solar observations", which has been accepted for publication in the Astrophysical Journal. 

The short description of the animation is as follows:

Fig2.mp4: Snapshot from the animation of the Fe I 6173 Å line-of-sight magnetic field maps showing emerging magnetic fields in the photosphere. The left panel shows an emerging ephemeral region in the SST data set recorded in 2015. The middle and the right panels display a larger and a smaller emerging field in the Bifrost simulation at 100 km horizontal resolution, respectively. For easier visual comparison, the magnetic field maps are scaled to the same values ±50 G, and the field-of-views expand to the same extent. The purple contours enclose footpoints of the emerging bipoles. The animation runs from Δt = 0:00:00 to Δt = 2:32:10.

Notes

The data used in the manuscript and shown here in the animation were acquired through an IRIS and SST coordination on 2015 October 11 and 2016 Aug 3. The simulations described in this paper were generated with the Bifrost code (Gudiksen et al. 2011). IRIS is a NASA Small Explorer Mission developed and operated by LMSAL with mission operations executed at NASA Ames Research Center and major contributions to downlink communications funded by ESA and the Norwegian Space Centre. MG, VHH, BDP, and ASD are supported by NASA contract NNG09FA40C (IRIS). MG, VHH, and BDP were also supported by NASA grant 80NSSC20K1272. The Swedish 1-m Solar Telescope (SST) is operated on the island of La Palma by the Institute for Solar Physics of Stockholm University in the Spanish Observatory del Roque de los Muchachos of the Instituto de Astrofísica de Canarias. The SST is co-funded by the Swedish Research Council as a national research infrastructure (registration number 4.3-2021-00169). This research is supported by the Research Council of Norway, project number 325491, and through its Centres of Excellence scheme, project number 262622.
