Solar Physics Group

The IAA's Solar Physics Group (SPG) is a dynamic research group whose main scientific interests root in solar spectropolarimetry and magnetic fields from all the three points of view: theoretical, observational, and instrumental. Investigations and developments are carried out on: 1) the radiative transfer equation (RTE) for polarized light in the presence of magnetic fields; 2) the inversion of the RTE for its use on the interpretation of spectropolarimetric measurements; 3) the structure and physical nature of photospheric magnetic structures like plage and network flux tubes, the umbra, the penumbra, and the moat of sunspots, and the internetwork magnetic fields; 4) the evolution of the solar cycle from a theoretical point of view; and 5) the design, development, and construction of solar instrumentation.
