Convective Instability Of The Solar Corona: Why The Solar Wind Blows
Joseph Lemaire
Chapman's (1957) conductive model of the solar corona is characterized by a temperature varying as r**(-2/7) with heliocentric distance r. The density distribution in this non-isot…
Half a Century of Kinetic Solar Wind Models
Joseph Lemaire
I outline the development of four generations of kinetic models, starting with Chamberlain's solar breeze exospheric model. It is shown why this first kinetic model did not give ap…
Coronal Inflows and Giant Polar Plumes
R. Pinto, R. Grappin, J. Leorat
We present the first results of simulations of giant polar plumes and coronal flows. We use a 2.5D axisymmetric MHD numerical model of an isothermal corona and slow solar wind. A p…
Solar wind turbulent spectrum from MHD to electron scales
O. Alexandrova, J. Saur, C. Lacombe +5
Turbulent spectra of magnetic fluctuations in the free solar wind are studied from MHD to electron scales using Cluster observations. We discuss the problem of the instrumental noi…
Coupling Photosphere and Corona: Linear and Turbulent Regimes
A. Verdini, R. Grappin, M. Velli
In a recent work Grappin et al. [1] have shown that low- frequency movements can be transmitted from one footpoint to the other along a magnetic loop, thus mimicking a friction eff…
Turbulence, Energy Transfers and Reconnection in Compressible Coronal Heating Field-line Tangling Models
R. B. Dahlburg, A. F. Rappazzo, M. Velli
MHD turbulence has long been proposed as a mechanism for the heating of coronal loops in the framework of the Parker scenario for coronal heating. So far most of the studies have f…
