We present a visual determination of the number of bright points (BPs) existing in the quiet Sun, which are structures though to trace intense kG magnetic...
Magnetic cycles and rotation periods of late-type stars from photometric time series
Aims: We investigate the photometric modulation induced by magnetic activity cycles and study the relationship between rotation period and activity cycle(s) in...
Magnetic diffusion in solar atmosphere produces measurable electric fields
The efficient release of magnetic energy in astrophysical plasmas, such as during solar flares, can in principle be achieved through magnetic diffusion, at a...
Magnetic field amplification and structure formation by the Rayleigh-Taylor instability
We report our results from a set of high-resolution, two-fluid, non-linear simulations of the magnetized Rayleigh Taylor instability (RTI) at the interface...
Magnetic Field Components Analysis of the SCUPOL 850 μm Polarization Data Catalog
We present an extensive analysis of the 850 μm polarization maps of the SCUBA Polarimeter Legacy (SCUPOL) Catalogue produced by Matthews et al., focusing...
Magnetic Field Diagnostics in the Solar Upper Atmosphere
The magnetic field is the main driver of the activity in the solar upper atmosphere, but its measurement is notoriously difficult. In order to determine the...
Magnetic field diagnostics of prominences with the Mg II k line 3D Stokes inversions versus traditional methods
The Mg II k resonance line is commonly used for diagnosing the solar chromosphere. We theoretically investigated its intensity and polarization in solar...
Magnetic field emergence in mesogranular-sized exploding granules observed with sunrise/IMaX data
We report on magnetic field emergences covering significant areas of exploding granules. The balloon-borne mission Sunrise provided high spatial and temporal...
