Classification of magnetized star--planet interactions: bow shocks, tails, and inspiraling flows

, 2015
Close-in exoplanets interact with their host stars gravitationally as well as via their magnetized plasma outflows. The rich dynamics that arises may result in distinct observable features.

Origin of electron cyclotron maser-induced radio emissions at ultra-cool dwarfs: magnetosphere-ionosphere coupling currents

, 2012
A number of ultra-cool dwarfs emit circularly polarised radio waves generated by the electron cyclotron maser instability. In the solar system such radio is emitted from regions of strong auroral magnetic field-aligned currents.

Magnetic Field and Plasma Asymmetries Between the Martian Quasi‐Perpendicular and Quasi‐Parallel Magnetosheaths

Geophysical Research Letters
The Martian magnetosheath acts as a conduit for mass and energy transfer between the upstream solar wind and its induced magnetosphere. However, our understanding of its global properties remains limited. Using 9 years of data from NASA's Mars Atmosphere

Solar wind origin of terrestrial water

, 2011
The origin of the Earth water reserves during the evolution of the planet is one of the big miracles in geophysics. Common explanations are storage of water in the Earth mantle at a time when the crust had not yet formed and depositing of water by comets

Kinetic-scale magnetic turbulence and finite Larmor radius effects at Mercury

, 2011
We use a nonstationary generalization of the higher-order structure function technique to investigate statistical properties of the magnetic field fluctuations recorded by MESSENGER spacecraft during its first flyby (01/14/2008) through the near Mercury ...

Parameters of current systems in the magnetosphere as derived from observations of cosmic rays during the June 2015 magnetic storm

Solar-Terrestrial Physics, 2017
Basing on measurements of cosmic rays at the worldwide network of stations, we calculate variations in the planetary system of geomagnetic cutoff rigidity for the 2015 June moderate geomagnetic storm.

The Response of Broadband Kilometric Radiation to Compressions of the Jovian Magnetosphere

The Astrophysical Journal
In the planetary magnetosphere, plasma waves act as the medium for particles to transfer energy. Jupiter is the largest planet in our solar system, and the giant magnetosphere is full of energetic particles, producing intense radio emissions.

Generation of auroral turbulence through the magnetosphere–ionosphere coupling

New Journal of Physics, 2016
The shear Alfvén waves coupled with the ionospheric density fluctuations in auroral regions of a planetary magnetosphere are modeled by a set of the reduced magnetohydrodynamic and two-fluid equations. When the drift velocity of the magnetized plasma due

Comparative studies of planetary magnetospheres

Eos, Transactions American Geophysical Union, 1992
Three recent “flyby” spacecraft encounters of planetary magnetospheres have provided new glimpses of the broad spectrum of plasma behaviors that occur within such environments. Voyager 2's encounter with Neptune in August 1989 and Galileo's grav itational assist encounters with Venus in February 1990 and Earth in December 1990 have revealed significant

Enhanced response of thermospheric cooling emission to negative pressure pulse

Scientific Reports
Nitric oxide (NO) emission via 5.3 µm wavelength plays dominant role in regulating the thermospheric temperature due to thermostat nature. The response of NO 5.3 mm emission to the negative pressure impulse during November 06–09, 2010 is studied by using
