On the self-consistent model of the axisymmetric radio pulsar magnetosphere

, 1998
We consider a model of axisymmetric neutron star magnetosphere. In our approach, the current density in the region of open field lines is constant and the returning current flows in a narrow layer along the separatrix.

Jupiter's X-ray and EUV auroras monitored by Chandra, XXM-Newton, and Hisaki satellite [PDF]

, 2016
Jupiter's X-ray auroral emission in the polar cap region results from particles which have undergone strong field-aligned acceleration into the ionosphere.

Ultra-Low Frequency Waves of Foreshock Origin Upstream and Inside of the Magnetospheres of Earth, Mercury, and Saturn Related to Solar Wind–Magnetosphere Coupling

Universe
This review examines ultra-low frequency (ULF) waves across different planetary environments, focusing on Earth, Mercury, and Saturn. Data from spacecraft missions (CHAMP, Swarm, and Oersted for Earth; MESSENGER for Mercury; and Cassini for Saturn ...

Analyzing Geomagnetic Data From the Dusheti Observatory During the Intense Magnetic Storms of 2024

Earth and Space Science, Volume 13, Issue 2, February 2026.
Abstract Geomagnetic storms, intense disturbances in the Earth's magnetosphere, pose risks to both technology and human activity in space. In this study, we analyzed geomagnetic field measurements from the Dusheti Observatory in Georgia during the intense geomagnetic storms of March 3, March 24, and 11 May 2024.

Storm time dynamics of ring current protons: Implications for the long‐term energy budget in the inner magnetosphere

, 2015
Our investigation of the long‐term ring current proton pressure evolution in Earth's inner magnetosphere based on Van Allen Probes data shows drastically different behavior of the low‐ and high‐ energy components of the ring current proton population ...

Protoplanet magnetosphere interactions [PDF]

Astronomy & Astrophysics, 2006
In this paper, we study a simple model of an orbiting protoplanet in a central magnetospheric cavity, the entry into such a cavity having been proposed as a mechanism for halting inward orbital migration. We have calculated the gravitational interaction of the protoplanet with the magnetosphere using a local model and determined the rate of evolution ...

A watercolor painting of northern lights seen above Japan on 11 February 1958

Journal of Space Weather and Space Climate, 2019
A 61 years old watercolor painting of red aurora was recently provided from a Japanese citizen, and it contributed to understand the detailed time evolution around the peak time of the large magnetic storm on 11 February 1958.

Applying Hpo Indices to Empirical Thermospheric Density Models During Geomagnetic Storms

Earth and Space Science, Volume 13, Issue 2, February 2026.
Abstract Accurate atmospheric drag modeling is essential for precise orbit determination and prediction of Low Earth Orbit satellites. A key component is the thermospheric density, typically estimated using empirical models driven by geomagnetic activity indices such as the 3‐hr Kp or ap.
