temperature, however, changes in a completely unexpected way: above the temperature minimum, it begins to rise to as high as 25,000 K at the top of the chromospheric
It would be difficult for us to distinguish such purposeful, nefarious camouflage from naturally occurring chromospheric
Alfvenic waves strong enough to power the solar wind.
The techniques introduced here will enable reliable and robust measurements of chromospheric
magnetic fields, shedding new light on this enigmatic but centrally important layer of the solar atmosphere.
Such a model can account for the presence of both He I and He II emission lines in the chromospheric
On Aug 8 a spectacular 'horned' dark filament graced the SE quadrant which was still present the following day, matching the alignment of chromospheric
disturbance in the SW quadrant.
They cover interior, convection, and dynamo, the formation and evolution of sunspots and active regions; flux emergence and submergence; waves, reconnection, and chromospheric
and coronal heating; magnetic fields as structuring agents of the solar atmosphere; flares, eruptions, and particle acceleration; solar wind and the interplanetary space; and Hinode and Solar Dynamics Observatory.
As this binary has a spectral classification of G4V I suggest the dip in the light curve is due to chromospheric
The heated chromospheric
matter responds by evaporating into the corona, where it can increase the gas density within a flaring loop a thousandfold.
Images with Markov Random Fields.
Starting at roughly 6,000 kelvins at the sun's surface, the solar atmosphere's temperature falls to nearly 4,300 kelvins at an altitude of 500 kilometers before rising to typical chromospheric
As the chromospheric
ribbon swept across the region signaling the reconnection of the field lines that were opened during the eruption, the same cells reappeared immediately behind the ribbon.
