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 ...

The Initial Mass Function of the Galactic Early-type Field Stars Based on the LAMOST Survey
The Astrophysical JournalResearch on the high-mass end of the initial mass function (IMF) has been limited due to a scarcity of samples. Recently, Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST), as the most efficient spectroscopic telescope, has provided new ...

The interplanetary magnetic field influences mid-latitude surface atmospheric pressure
Environmental Research Letters, 2013 The existence of a meteorological response in the polar regions to fluctuations in the interplanetary magnetic field (IMF) component B _y is well established.

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.

A Possible Solution for the $M/L-\mathrm{[Fe/H]}$ Relation of Globular Clusters in M31. II. the Age-Metallicity Relation [PDF]
, 2017 This is the second of a series of papers in which we present a new solution to reconcile the prediction of single stellar population (SSP) models with the observed stellar mass-to-light ($M/L$) ratios of globular clusters (GCs) in M31 and its trend with ...

Business Strategy and the Environment, EarlyView.ABSTRACT This study investigated whether superior environmental, social, and governance (ESG) practices enhance corporate value and market efficiency under various economic theories. Using a multi‐country panel of 31 economies from 2015 to 2022, we find that both ESG performance and disclosure improve intrinsic value and mitigate equity misvaluation ...
