Effects of the integrated galactic IMF on the chemical evolution of the solar neighbourhood [PDF]

Monthly Notices of the Royal Astronomical Society, 2010
The initial mass function determines the fraction of stars of different intial mass born per stellar generation. In this paper, we test the effects of the integrated galactic initial mass function (IGIMF) on the chemical evolution of the solar ...

Evolution of IMF By Induced Asymmetries: The Role of Tail Reconnection

Journal of Geophysical Research: Space Physics, 2021
North‐south asymmetries arise in the magnetosphere‐ionosphere system when a significant east‐west (By) component is present in the interplanetary magnetic field (IMF).

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

Frontiers 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 ...

Multi-scale evolution of Kelvin–Helmholtz waves at the Earth's magnetopause during southward IMF periods [PDF]

Physics of Plasmas, 2022
At the Earth’s low-latitude magnetopause, the Kelvin–Helmholtz instability (KHI), driven by the velocity shear between the magnetosheath and magnetosphere, has been frequently observed during northward interplanetary magnetic field (IMF) periods. However,

ALMA-IMF. VI. Investigating the origin of stellar masses: Core mass function evolution in the W43-MM2&MM3 mini-starburst [PDF]

Astronomy & Astrophysics, 2022
Among the most central open questions regarding the initial mass function (IMF) of stars is the impact of environment on the shape of the core mass function (CMF) and thus potentially on the IMF.

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

Earth 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 ...

Chemical evolution of ultra-faint dwarf galaxies in the self-consistently calculated integrated galactic IMF theory [PDF]

Astronomy & Astrophysics, 2020
The galaxy-wide stellar initial mass function (gwIMF) of a galaxy in dependence on its metallicity and star formation rate can be calculated by the integrated galactic IMF (IGIMF) theory.

ALMA-IMF. V. Prestellar and protostellar core populations in the W43 cloud complex [PDF]

Astronomy & Astrophysics, 2023
The origin of the stellar initial mass function (IMF) and its relation with the core mass function (CMF) are actively debated issues with important implications in astrophysics.

Global Asymmetry in ΔX Variations During the 06 April 2000 Geomagnetic Storm: Relative Roles of IMF Bz and By [PDF]

Journal of Geophysical Research: Space Physics, 2023
This investigation is directed to understand the asymmetry in ΔX variations caused due to the relative roles played by Interplanetary Magnetic Field (IMF) Bz and IMF By in a particular interval (22:22–22:55 UT), during the main phase of a strong ...
