What happens when the geomagnetic field reverses?
Joseph F. Lemaire, Fred Singer
During geomagnetic field reversals the radiation belt high-energy proton populations become depleted. Their energy spectra become softer, with the trapped particles of highest ener…
The effect of a southward interplanetary magnetic field on Störmer's allowed regions
Joseph F. Lemaire
The motion of a charged particle in a magnetic dipole has first been studied by Stormer. The different applications of Stormer's theory to aurorae, cosmic rays and Van Allen radiat…
Coronal temperature profiles obtained from kinetic models and from coronal brightness measurements obtained during solar eclipses
V. Pierrard, K. Borremans, J. F. Lemaire
Coronal density, temperature and heat flux distributions for the equatorial and polar corona have been deduced by Lemaire [2012] from Saito's model of averaged coronal white light…
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…
Determination of coronal temperatures from electron density profiles
J. F. Lemaire
The most popular method for determining coronal temperatures is the scale-height-method (shm). It is based on electron density profiles inferred from White Light (WL) brightness me…
