Current sheets, plasmoids and flux ropes in the heliosphere. Part II: Theoretical aspects

O. Pezzi, F. Pecora, J. le Roux +13

Our understanding of processes occurring in the heliosphere historically began with reduced dimensionality - one-dimensional (1D) and two-dimensional (2D) sketches and models, whic…

Evolution of the solar wind speed with heliocentric distance and solar cycle. Surprises from Ulysses and unexpectedness from observations of the solar corona

O. V. Khabarova, V. N. Obridko, R. A. Kislov +5

An extensive analysis of Ulysses observations of the solar wind speed V from 1990 to 2008 is undertaken. It is shown that the evolution of V with heliocentric distance r depends su…

The Solar Flare Sulphur Abundance from RESIK Observations

J. Sylwester, B. Sylwester, K. J. H. Phillips +1

The RESIK instrument on {\em CORONAS-F} spacecraft observed several sulphur X-ray lines in three of its four channels covering the wavelength range 3.8-6.1 Å during solar flares. T…

The Solar Flare Chlorine Abundance from RESIK X-ray Spectra

B. Sylwester, K. J. H. Phillips, J. Sylwester +1

The abundance of chlorine is determined from X-ray spectra obtained with the RESIK instrument on {\em CORONAS-F} during solar flares between 2002 and 2003. Using weak lines of He-l…

The solar X-ray continuum measured by RESIK

K. J. H. Phillips, J. Sylwester, B. Sylwester +1

The solar X-ray continuum emission at five wavelengths between 3.495 Angstroms and 4.220 Angstroms for 19 flares in a seven-month period in 2002--2003 was observed by the RESIK cry…

Highly Ionized Potassium Lines in Solar X-ray Spectra and the Abundance of Potassium

J. Sylwester, B. Sylwester, K. J. H. Phillips +1

The abundance of potassium is derived from X-ray lines observed during flares by the RESIK instrument on the solar mission CORONAS-F between 3.53 A and 3.57 A. The lines include th…
