PublicaciónThe role of the chromospheric magnetic canopy in the formation of a sunspot penumbra
Context. While it is conjectured that a chromospheric canopy plays a role in penumbra formation, it has been difficult to find observational evidence of the...

PublicaciónThe Spectrum of Fluctuations across Penumbral Filaments
We estimate the typical spectrum of spatial fluctuations of intensity due to the penumbral filaments. High angular resolution continuum images are used (cut-off...

CharlaThe stochastic, intermittent nature of quiet Sun magnetism
The quiet Sun (the 99%, or more, of the solar surface not covered by sunspots or active regions) is receiving increased attention in recent years; its role on...

PublicaciónThe Temperature - Magnetic Field Relation in Observed and Simulated Sunspots
Observations of the relation between continuum intensity and magnetic field strength in sunspots have been made for nearly five decades. This work presents full...

PublicaciónThermal-magnetic relation in a sunspot and a map of its Wilson depression
We present relations between thermal and magnetic quantities in a simple, isolated sunspot, as deduced from the inversion of 1.56 μm spectropolarimetric data...

PublicaciónThermal-magnetic relation of a sunspot as inferred from the inversion of 1.5 μm spectral data
We present the thermal-magnetic relation in a simple, isolated sunspot deduced from the inversion of 1.56 μm spectropolarimetric data. Due to the high Zeeman...

PublicaciónThree dimensional structure of a regular sunspot from the inversion of IR Stokes profiles
The magnetic, thermal and velocity structure of a regular sunspot, observed close to solar disk center is presented. Spectropolarimetric data obtained with the...

PublicaciónThree-dimensional structure of a sunspot light bridge
Context. Active regions are the most prominent manifestations of solar magnetic fields; their generation and dissipation are fundamental problems in solar...
