The Quiet-Sun Photosphere and Chromosphere [PDF]

Philosophical Transactions Series A, Mathematical, Physical, and Engineering Sciences, 2012
Abstract The overall structure and the fine structure of the solar photosphere outside active regions are largely understood, except possibly the important roles of a turbulent near-surface dynamo at its bottom, internal gravity waves at its top and small-scale vorticity. Classical one-dimensional static radiation-escape modelling has

Rotational shear in the low photosphere of the Sun

Proceedings of the International Astronomical Union, 2023
AbstractWe present a new method to measure the rotational height gradient in the solar photosphere. The method is inspired from differential interferometric techniques, we applied it to spectroscopic observations in the FeI 630.15 nm obtained at the solar telescope THEMIS which is equipped with an efficient adaptive optics system.

Magnetic flux transport in the photosphere of the Sun

2020
<p>On the basis of the synoptic maps of the photospheric magnetic field obtained by the National Solar Observatory Kitt Peak for 1978-2016, a latitude-time diagram of the magnetic field was built. When averaging intensity values over the heliolongitude, the magnetic field sign was taken into account.
