Current Systems in Planetary Magnetospheres and Ionospheres
Space Science Reviews, 2010The interaction of planets with the solar wind produces a diversity of current systems, yet these can be classified into only a few different types, which include ionospheric currents, currents carried by magnetospheric boundaries like the magnetopause or ionopause, magnetotail currents, and currents flowing inside the magnetospheres, like ring ...

Dissociative Recombination in Planetary Ionospheres [PDF]
, 1993 Ionization in planetary atmospheres can be produced by solar photoionization, photoelectron impact ionization, and, in auroral regions, by impact of precipitating particles. This ionization is lost mainly in dissociative recombination (DR) of molecular ions.

Radio Occultation Experiment for Probing Planetary Ionospheres
2019 URSI Asia-Pacific Radio Science Conference (AP-RASC), 2019Radio occultation (RO) is an important measurement technique for studying planetary atmospheres. It is based on the measurement of the frequency shift of the received radio signal from the spacecraft, caused by the bending of radio waves in the atmosphere.

Dications in the planetary ionospheres [PDF]
, 2006 The planetary ionosphere models usually consider singly charged ions only and neglect doubly charged ions and especially the molecular ones since they were thought to be unstable in ionospheric conditions. Generally speaking, doubly charged ions are difficult to detect by mass spectrometry because their q/m number is the same as other more abundant ...

Sources of Planetary Ionospheres [PDF]
, 1994 The sources of dayside and nightside ionospheres of the terrestrial and outer planets and their satellites are discussed. The sources of dayside ionospheres include photoionization of neutral thermospheric constituents by solar ultraviolet and x-ray photons.

Models of Planetary Ionospheres [PDF]
, 1973 The distribution of charged particles (electrons and ions) in a planetary ionosphere is governed by the equation of continuity $$\frac{{\partial N}}{{\partial t}} = q - L(N) - \nabla \cdot (Nv)$$ (6-1) A steady state situation (∂N/∂t = 0) can often be assumed, except near sunrise and sunset or during other rapidly varying situations such as a
