Telecommunications in cometary environments [PDF]

Propagation effects on telecommunications in a cometary environment include those due to dust, the inhomogeneous plasma of the coma and tail, and ionization generated by impact of neutral molecules and dust on the spacecraft.

Magnetic field and wind of Kappa Ceti: towards the planetary habitability of the young Sun when life arose on Earth

, 2016
We report magnetic field measurements for Kappa1~Cet, a proxy of the young Sun when life arose on Earth. We carry out an analysis of the magnetic properties determined from spectropolarimetric observations and reconstruct its large-scale surface magnetic

The effects of crustal magnetic fields and solar EUV flux on ionopause formation at Mars

, 2019
We study the ionopause of Mars using a database of 6,893 ionopause detections obtained over 11 years by the MARSIS (Mars Advanced Radar for Subsurface and Ionosphere Sounding) experiment.

Planetary Waves in the Thermosphere-Ionosphere System.

Journal of geomagnetism and geoelectricity, 1996
In the limit of an isothermal atmosphere without dissipation, the equations governing atmospheric motions admit solutions corresponding to “free” (unforced) oscillations for discrete zonal wavenumbers and periods. Global oscillations belonging to the rotational subclass are referred to as free Rossby waves or Rossby normal modes.

Plasma Waves Can Gain Energy from Neutrals in Partially Ionized Plasmas

The Astrophysical Journal
Partially ionized plasmas are widely present in astrophysical and space plasmas, and ion-neutral collisions have an important impact on the plasma dynamics, such as electrostatic wave propagation.
