Induced magnetosphere of Mars responds fast to interplanetary magnetic field rotation [PDF]

open access: yesNature Communications
Interactions between the ionospheres of unmagnetized bodies and ambient plasma flows form induced magnetospheres. The induced magnetosphere is generally affected by external magnetic fields. Observations of response processes of the induced magnetosphere

The «Group of Twenty», IMF and EU and Reforming of Global Governance

open access: yesVestnik MGIMO-Universiteta, 2014
This article is devoted to the process of reforming the global financial system and world economic organizations since the foundation of the International Monetary Fund at the Bretton Woods Conference in 1944 to present time.

Stellar Initial Mass Function (IMF) Probed with Supernova Rates and Neutrino Background: Cosmic-average IMF Slope Is ≃2–3 Similar to the Salpeter IMF

open access: yesThe Astrophysical Journal, 2023
The stellar initial mass function (IMF) is expressed by ϕ ( m ) ∝ m ^− ^α with the slope α , and known as a poorly constrained but very important function in studies of star and galaxy formation. There are no sensible observational constraints on the IMF

Upstream proton cyclotron waves: occurrence and amplitude dependence on IMF cone angle at Mars — from MAVEN observations

open access: yesEarth and Planetary Physics, 2020
Proton cyclotron waves (PCWs) can be generated by ion pickup of Martian exospheric particles in the solar wind. The solar wind ion pickup process is highly dependent on the “IMF cone angle” — the angle between the solar wind velocity and the ...

Interplanetary Magnetic Field Effect on the Location of the Martian Bow Shock: MAVEN Observations

open access: yesThe Astrophysical Journal, 2023
The Martian bow shock (BS) is generated with the mass-loading and magnetic pileup processes when the solar wind interacts with the Martian ionosphere. In this vein, the interplanetary magnetic field (IMF) frozen in the solar wind can affect the location ...

Diffusive Plasma Transport by the Magnetopause Kelvin-Helmholtz Instability During Southward IMF

open access: yesFrontiers in Astronomy and Space Sciences, 2022
At the Earth’s low-latitude magnetopause, the Kelvin-Helmholtz (KH) waves, which are driven by the super-Alfvénic velocity shear across the magnetopause, have been frequently observed during periods of northward interplanetary-magnetic-field (IMF) and ...

Statistical Birkeland current distributions from magnetic field observations by the Iridium constellation [PDF]

open access: yesAnnales Geophysicae, 2008
We present a statistical analysis of Birkeland currents derived from Iridium magnetometer data acquired in the Northern Hemisphere to determine the dependence of large-scale currents on the interplanetary magnetic field (IMF) direction.

The Central Dark Matter Fraction of Massive Early-Type Galaxies

open access: yesFrontiers in Astronomy and Space Sciences, 2022
Dark matter (DM) is predicted to be the dominant mass component in galaxies. In the central region of early-type galaxies it is expected to account for a large amount of the total mass, although the stellar mass should still represent the majority of the

What went wrong? The evolution of the IMF 1941-1961

open access: yesPSL Quarterly Review, 2013
Despite its promising start in 1946-47, the new IMF soon ceased to fulfil its expected role for almost nine years. An exploration is provided for the latter in the wider context of international economic cooperation. It was not until 1961 that the Fund's

Three-dimensional MHD simulation of interplanetary magnetic field changes at 1 AU as a consequence of simulated solar flares [PDF]

open access: yesAnnales Geophysicae, 1996
A fully three-dimensional (3D), time-dependent, MHD interplanetary global model (3D IGM) has been used, for the first time, to study the relationship between different forms of solar activity and transient variations of the north-south component, Bz ...
