The evolution of luminosity, colour, and the mass-to-luminosity ratio of Galactic open clusters - Comparison of discrete vs. continuous IMF models [PDF]

, 2010
Context. We found in previous studies that standard simple stellar population (SSP) models are unable to describe or explain the colours of Galactic open clusters both in the visible and in the near-infrared (NIR) spectral range.

Evolution of the global aurora during positive IMF Bz and varying IMF By conditions

Journal of Geophysical Research: Space Physics, 1997
The DE 1 imaging instrumentation provides a full view of the entire auroral oval every 12 min for several hours during each orbit. We examined five examples of global evolution of the aurora that occurred during the northern hemisphere winter of 1981‐1982 when the z component of the interplanetary magnetic field was positive and the y component was ...

Variability of Draped Interplanetary Magnetic Field in the Subsolar Martian Ionosphere

The Astrophysical Journal, 2023
In the absence of an intrinsic magnetic field, the solar wind interacts directly with the Martian atmosphere, and the interplanetary magnetic field (IMF) drapes around the ionosphere. With the aid of multi-instrument measurements from Mars Atmosphere and

An Integrated Picture of Star Formation, Metallicity Evolution, and Galactic Stellar Mass Assembly

, 2008
We present an integrated study of star formation and galactic stellar mass assembly from z=0.05-1.5 and galactic metallicity evolution from z=0.05-0.9 using a very large and highly spectroscopically complete sample selected by rest-frame NIR bolometric ...

Open Magnetic Fields in the Martian Magnetosphere Revealing Dipole-like Intrinsic Magnetic Fields at Mars

The Astrophysical Journal Letters, 2023
Mars’s magnetosphere is hybrid, having contributions from both an induced magnetosphere like Venus and the localized crustal magnetic fields. However, the planetary fields also include large-scale, more global components.

Aeos: The Impact of Population III Initial Mass Function and Star-by-star Models in Galaxy Simulations

The Astrophysical Journal
We explore the effect of variations in the Population III initial mass function (IMF) and star-by-star feedback on early galaxy formation and evolution using the A eos simulations. We compare simulations with two different Population III IMFs: M _char  =

Statistical Activities of IMF: A Factor of Global Financial Stabilization in the Post-Crisis Period

Статистика України, 2018
The areas of transformation of the statistical activities of the International Monetary Fund (IMF) in the post-crisis period are outlined, and their contribution in the global financial stabilization is assessed.

The galaxy stellar mass-star formation rate relation: Evidence for an evolving stellar initial mass function?

, 2008
The evolution of the galaxy stellar mass--star formation rate relationship (M*-SFR) provides key constraints on the stellar mass assembly histories of galaxies.

The Gaia-ESO Survey: membership and Initial Mass Function of the Gamma Velorum cluster [PDF]

, 2016
Understanding the properties of young open clusters, such as the Initial Mass Function (IMF), star formation history and dynamic evolution, is crucial to obtain reliable theoretical predictions of the mechanisms involved in the star formation process. We
