Further investigation of the effect of upstream solar-wind fluctuations on solar-wind/magnetosphere coupling: Is the effect real?

open access: yesFrontiers in Astronomy and Space Sciences, 2023
There is a general consensus that fluctuations in the solar wind magnetic field and/or the Alfvenicity of the solar wind drive a solar wind-magnetosphere interaction.

Pulsar Magnetosphere: Variation Priciple, Singularities, Estimate of Power [PDF]

open access: yes, 2005
We formulate variation principle for force-free magnetosphere of an inclined pulsar: ${\cal E} +{\bf \Omega}\cdot {\bf M}$ ($\cal E$, ${\bf M}$ are electromagnetic energy and angular momentum, ${\bf \Omega}$ is the angular velocity of a star) is ...

SIMULATION STUDY OF THE ENERGETIC NEUTRAL ATOM (ENA) IMAGING MONITORING OF THE GEOMAGNETOSPHERE ON A LUNAR BASE

open access: yesSolar-Terrestrial Physics, 2021
Since the moon’s revolution cycle is exactly the same as its rotation cycle, we can only see the moon always facing Earth in the same direction. Based on the clean particle radiation environment of the moon, a neutral atomic telemetry base station could ...

Faraday Rotation in Pulsar Magnetosphere

open access: yes, 2011
The magnetosphere of a pulsar is composed of relativistic plasmas streaming along the magnetic field lines and corotating with the pulsar. We study the intrinsic Faraday rotation in the pulsar magnetosphere by critically examining the wave modes and the ...

Low‐dose X‐ray radiation induces an adaptive response: A potential countermeasure to galactic cosmic radiation exposure

open access: yesExperimental Physiology, EarlyView.
Abstract Space exploration involves many dangers including galactic cosmic radiation (GCR). This class of radiation includes high‐energy protons and heavy ionizing ions. NASA has defined GCR as a carcinogenic risk for long‐duration space missions. To date, no clear strategy has been developed to counter chronic GCR exposure.

Intensification of the Electron Zebra Stripes in the Earth's Inner Magnetosphere During Geomagnetic Storms

open access: yesGeophysical Research Letters
We examined rapid variations in the electron zebra stripe patterns, specifically at L = 1.5, over a three‐month duration, using twin Van Allen Probes within Earth's inner magnetosphere. During geomagnetically quiet intervals, these stripes exhibit a peak‐

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

open access: yesExperimental Physiology, EarlyView.
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

Current Flow and Pair Creation at Low Altitude in Rotation Powered Pulsars' Force-Free Magnetospheres: Space-Charge Limited Flow [PDF]

open access: yes, 2012
(shortened) We report the results of an investigation of particle acceleration and electron-positron plasma generation at low altitude in the polar magnetic flux tubes of Rotation Powered Pulsars, when the stellar surface is free to emit whatever charges

Solar Wind–Magnetosphere Coupling by the Kelvin–Helmholtz Instability at Mercury

open access: yesThe Astrophysical Journal
The Kelvin–Helmholtz instability (KHI) has been considered important in the energy transfer and momentum coupling between the solar wind and planetary magnetospheres.

Jovian Magnetospheric Injections Observed by the Hubble Space Telescope and Juno

open access: yesGeophysical Research Letters, 2023
We compare Hubble Space Telescope observations of Jupiter's FUV auroras with contemporaneous conjugate Juno in situ observations in the equatorial middle magnetosphere of Jupiter.
