A wealth of new experimental and theoretical results has been obtained in solar physics
since the first edition of this textbook appeared in 1989. Thus all nine chapters have been …

In this chapter we will briefly review the basic interactions between particles and magnetic
fields, the processes that occur on the Sun which are relevant for space weather as well as …

Aims. The aim of this paper is to analyse the validity of the Dopplergram and λ-meter
techniques for the Doppler diagnostics of solar photospheric velocities using the Ba II 4554 …

Aims. The purpose of this paper is to characterize the statistical properties of solar
granulation in the photosphere and low chromosphere up to 650 km. Methods. We use …

Observed variations of the magnetic field strength in sunspot umbrae consist of intrinsic
oscillations and" false" oscillations due to time-dependent opacity effects. Here we present …

Aims. We study the properties of solar granulation in a facular region from the photosphere
up to the lower chromosphere. Our aim is to investigate the dependence of granular …

Aims. We study the properties of waves in a facular region of moderate strength in the
photosphere and chromosphere. Our aim is to statistically analyse the wave periods, power …

Aims. The Si i 10 827 Å line is commonly used for spectropolarimetric diagnostics of the
solar atmosphere. First, we aim at quantifying the sensitivity of the Stokes profiles of this line …

Spicule oscillations involve high-frequency components with a typical period approximately
corresponding to 40–50 s. The typical timescale of the photospheric oscillation is a few …

This paper studies the dependence of the Ca ii H line core brightness on the strength and
inclination of the photospheric magnetic field, and on the parameters of convective and …
