For a long time radiative MHD simulations of entire sunspots from first principles were out of reach due to insufficient computing resources. Over the past 4...
Refinements to the Solar Polar Magnetic Flux: Implications from Inversion Methodologies
The magnetic fields in the solar polar region are important to our understanding of the internal dynamo process, the global coronal structure, and the origin of...
Response 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...
The solar abundance of chemical elements play an important role in addressing such important issues as the formation, structure, and evolution of the Sun and...
Solar Flare Ribbons Structured by Uncombed Chromospheric Loops
A part of the magnetic energy released during a flare is transported to the lower atmosphere. High-resolution observations show that flare ribbons, sites of...
Solar-cycle and Latitude Variations in the Internetwork Magnetism
The importance of the quiet-Sun magnetism is that it is always there to a greater or lesser extent, being a constant provider of energy, independently of the...
This contribution is a report on a test campaign carried out by the IAC, in collaboration with Construcciones Aeronauticas, S.A. (CASA) as a main contrac tor...
Spectropolarimetry of the Solar Mg II h and k Lines
We report on spectropolarimetric observations across the Mg II h and k lines at 2800 Å made by the Ultraviolet Spectrometer and Polarimeter on board the Solar...
Statistical 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...
