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

The 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 ...

The Star Formation Epoch of the Most Massive Early-Type Galaxies [PDF]

, 2006
We present new Keck spectroscopy of early-type galaxies in three galaxy clusters at z~0.5. We focus on the fundamental plane (FP) relation, and combine the kinematics with structural parameters determined from HST images.

Reverse dynamical evolution of Eta Chamaeleontis [PDF]

, 2013
In the scope of the star formation process, it is unclear how the environment shapes the initial mass function (IMF). While observations of open clusters propose a universal picture for the IMF from the substellar domain up to a few solar masses, the ...

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

Annales 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.

Testing the universal stellar IMF on the metallicity distribution in the bulges of the Milky Way and M31 [PDF]

, 2007
We test whether the universal initial mass function (UIMF) or the integrated galaxial IMF (IGIMF) can be employed to explain the metallicity distribution (MD) of giants in the Galactic bulge.

The Central Dark Matter Fraction of Massive Early-Type Galaxies

Frontiers 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

Transforming the Functions of IMF and Cooperation with Russia [PDF]

Современная Европа, 2022
The article explores the evolution of the IMF’s role in the regulation of international monetary system. It is observed that the conflict between the competencies of the IMF as an international regulator, empowered to intervene in monetary and financial ...

Transition of the Stellar Initial Mass Function Explored with Binary Population Synthesis [PDF]

, 2013
The stellar initial mass function (IMF) plays a crucial role in determining the number of surviving stars in galaxies, the chemical composition of the interstellar medium, and the distribution of light in galaxies.

IMF - metallicity: a tight local relation revealed by the CALIFA survey [PDF]

, 2015
Variations in the stellar initial mass function (IMF) have been invoked to explain the spectroscopic and dynamical properties of early-type galaxies. However, no observations have yet been able to disentangle the physical driver. We analyse here a sample

How does a low-mass cut-off in the stellar IMF affect the evolution of young star clusters? [PDF]

, 2014
We investigate how different stellar initial mass functions (IMFs) can affect the mass-loss and survival of star clusters. We find that IMFs with radically different low-mass cut-offs (between 0.1 and 2 M⊙) do not change cluster destruction time-scales ...
