Magnetic flux in the inter-network quiet Sun from comparison with numerical simulations

J. Sanchez Almeida

Khomenko et al. estimate the mean magnetic field strength of the quiet Sun to be 20 G. The figure is smaller than several existing estimates, and it comes from the comparison betwe…

The distribution of Quiet Sun magnetic field strengths from 0 to 1800 G

I. Dominguez Cerdena, J. Sanchez Almeida, F. Kneer

The quiet Sun photospheric plasma has a variety of magnetic field strengths going from zero to 1800 G. The empirical characterization of these field strengths requires a probabilit…

On the Sr I 4607 A Hanle depolarization signals in the quiet Sun

J. Sanchez Almeida

The Hanle depolarization signals of Sr 4607 A have been used to estimate the unsigned magnetic flux and magnetic energy existing in the quiet Sun photosphere. However, the Sr 4607…
