CharlaResponse of the solar atmosphere to the photospheric plasma motion
The dynamics of the solar atmosphere is largely controlled by its magnetic coupling to the photosphere of the Sun. Since the solar magnetic field is complex...

PublicaciónStatistical properties of magnetic fields in intranetwork
We report a study of the quiet sun's magnetic field based on high-resolution infrared spectropolarimetric observations (TIP/VTT). We find that in almost 50% of...
