Upstream IMF Influence on Closed Magnetic Field Orientation on Mars
Geophysical Research Letters, Volume 52, Issue 13, 16 July 2025.Abstract Closed magnetic fields play an important role in plasma transport and atmospheric escape from the Martian dayside ionosphere. Leveraging in‐situ magnetic field data from the Mars Atmosphere and Volatile EvolutioN (MAVEN) mission, we conduct a statistical analysis of closed magnetic field behavior under varying upstream conditions. Our findings

Enhanced Energetic Neutral Atom Imaging
Frontiers in Astronomy and Space Sciences, 2019 Over the past two decades, instruments designed to image plasmas in energetic neutral atom (ENA) emission have flown in space. In contrast to typical satellite-based in situ instruments, ENA imagers provide a global view of the magnetosphere because they

A correlative investigation of the propagation of ULF wave power through the dayside magnetosphere [PDF]
Three different ULF wave phenomena (azimuthally polarized Pc 3 pulsations, radially polarized Pc 4 pulsations, and solitary Pc 5 pulsations related to solar wind pressure pulses) were studied. The main problems covered are: (1) how do magnetospheric Pc 3-

Eos, Transactions American Geophysical Union, 1991 Research on the terrestrial magnetosphere, above 500 km, continues to focus on how energy gets from the solar wind into the magnetosphere and how it circulates through the magnetosphere. The prime candidate for energy coupling has long been magnetic merging in which the magnetic field that the solar wind carries from the Sun merges with the geomagnetic

Dependence of Plasmaspheric Hiss Power on ωpe/Ωce
Geophysical Research Letters, Volume 52, Issue 13, 16 July 2025.Abstract Plasmaspheric hiss waves play a key role in scattering energetic electrons and are often modeled in the inner magnetosphere using empirical hiss power maps parameterized by L shell. In this study, we compare the dependence of hiss power on both L shell (2 ≤ L ≤ 6) and the ratio of electron plasma frequency to electron gyrofrequency (ωpe/Ωce ...

, 2014 This book belongs to a series of online books summarizing the recent state Topological Geometrodynamics (TGD) and its applications. TGD can be regarded as a unied theory of fundamental interactions but is not the kind of unied theory as so called GUTs constructed by graduate students at seventies and eighties using detailed recipes for how to reduce ...

Geophysical Research Letters, Volume 52, Issue 13, 16 July 2025.Abstract The warm plasma cloak (WPC) is a plasma population located in the outer magnetosphere. It is composed primarily of electrons and H+ ${\mathrm{H}}^{+}$ ions with energies of tens to hundreds electronvolts and can contain significant amounts of O+ ${\mathrm{O}}^{+}$. We conduct a statistical survey of the WPC using 9 years of observations in the

The magnetorotational and Tayler instabilities in the pulsar magnetosphere
, 2017 The magnetospheres around neutron stars should be very particular because of their strong magnetic field and rapid rotation. A study of the pulsar magnetospheres is of a crucial importance since it is the key issue to understand how energy inflow to the ...
