International audience; Aims: This paper investigates the rotation rate of solar activity from a global point of view, considering daily index or flux, instead of individual structures. It determines the rotation rate variations inside the cycle by t

The three-dimensional (3D) reconstruction of magnetic configurations above the photosphere is consid- ered within the framework of the nonlinear force-free-field (FFF) model. The physical- computational algorithm pro- posed and tested incorporates, f

Using the exact solution methods developed and illustrated previously, we systematically explore (ω, k) space in order to determine all the unstable modes of velocity-shear-produced electromagnetic waves in magnetized, relativistic electron beams (h

The transcendental dispersion equation for electromagnetic waves propagating in the slow mode in sheared non-neutral relativistic cylindrical electron beams in strong applied magnetic fields is solved exactly. Thus, rather than truncated power series

International audience; We propose a process for calculating water vapor absorption in solar radiation transmission through the atmosphere, in order to rebuild a true solar line profile, blended with telluric lines, with very good accuracy. First, we

It is shown that the solar flare electron spectra in a large energy range fit well with a power law in energy. This is used as a basis to discuss the possible division of solar flares into various groups, and also to compare the spectra of electrons

An isobaric model is used to determine the spectrum of the neutral pi‐mesons produced in proton‐proton interaction. The angular distribution of isobars in the center‐of‐momentum system is taken to be isotropic or of the form A+Bcos2θ*. It is

The proposed model of particles transport in the solar atmosphere during flares consists in a low density plasmoid originating deep in the atmosphere and rising under magnetic and buoyancy forces. Confined particles are selectively released during th
