Due to the broad wings of the point spread function of the Wolter telescopes used in the Skylab mission for taking X-ray pictures of the solar corona, the images are blurred around bright emission regions. As a result, the maps of temperature and emi

A method is developed which for a certain day permits the approximate calculation of closed small and large scale magnetic field lines. From the photospheric longitudinal components of the magnetic field measured at this day normal components are der

Soft X-ray photographs of the Sun taken at O vii 21.6 A and in a spectral band ranging from 13.2 to 22.1 A have been analysed in order to establish spatially resolved maps of temperature and emission measure for several active regions in the corona.

The evolution of the energy distributions of fast flare electrons injected towards the chromosphere are computed by the Monte Carlo method for different depths. Using these distributions, power law bremsstrahlung spectra having spectral indices incre

X-ray images taken by the Hard X-Ray Imaging Spectrometer (HXIS) aboard SMM during the 1980, November 18 limb flare are analysed. The temporal and spatial evolutions of the X-radiation are described. They differ significantly for hard and soft X-rays

Assuming steady state conditions, we calculated the occupation of 20 levels of the ion Six as a function of the electron density and temperature taking into account collisional processes and spontaneous radiative ones. Between the two levels of the g
