We present a new method of Stokes inversion of spectropolarimetric data and evaluate it by taking the example of a SUNRISE/IMaX observation. An archive of synthetic Stokes profiles…
A Tale of Two Emergences: Sunrise II Observations of Emergence Sites in a Solar Active Region
Rebecca Centeno, Julian Blanco Rodriguez, Jose Carlos Del Toro Iniesta +11
In June 2013, the two scientific instruments onboard the second Sunrise mission witnessed, in detail, a small-scale magnetic flux emergence event as part of the birth of an active…
Kinematics of Magnetic Bright Features in the Solar Photosphere
Shahin Jafarzadeh, S. K. Solanki, R. H. Cameron +12
Convective flows are known as the prime means of transporting magnetic fields on the solar surface. Thus, small magnetic structures are good tracers of the turbulent flows. We stud…
