Background. One of the main tasks of the present-day breeding practice is the development of high-yielding intensive-type fodder crop cultivars for indoor feeding of livestock. Alfalfa, as a productive and high-protein crop, deserves special attentio

Alfven waves are considered in a radial flow and external magnetic field, which relates to some features of the solar wind near the critical point. The Alfven wave equation for the velocity perturbation is derived, showing that it has in general two

The application to the solar wind motivates the consideration of Alfven waves in a radial background magnetic field and radial mean flow, in two cases, viz., with velocity and magnetic field perturbations along parallels, or also with perturbations a

Magnetosonic-gravity waves in an isothermal non-dissipative atmosphere, with a uniform horizontal external magnetic field have been considered in the literature in two cases: (i) one-dimensional' magnetosonic-gravity waves, in the case of zero horizo

Alfven waves are considered in a radially inhomogeneous medium under a radial background magnetic field: In order for the latter to be divergence free, the magnetic field strength must decay like the inverse square of the distance; for the radial dep

This paper considers Alfvén waves in a radially stratified medium where all background quantities, namely mass density, magnetic field strength and mean flow velocity, depend only on the distance from the centre, the latter two being assumed to lie

We derive the Alfvén-wave equation for an atmosphere in the presence of a non-uniform vertical magnetic field and the Hall effect, allowing for Alfvén speed and ion gyrofrequency that may vary with altitude; the pair of coupled second-order differe

The linear propagation of Alfven waves in the solar wind is considered for arbitrary wavelengths, which may exceed the lengthscales of variation of (i) the mass density of the medium, (ii) strength and direction of the external magnetic field, (iii)

The present paper considers Alfven waves in an inhomogeneous medium, under a non-uniform external magnetic field and in the presence of a non-uniform flow, to obtain the wave equations for the velocity and magnetic field perturbations in the case of

Alfven waves are considered in a radial flow and external magnetic field, which relates to some features of the solar wind. Particular emphasis is put on the role of the Alfvenic critical point and propagation of the Alfven waves across this critical
