The Influence of General Relativity on the Spins of Celestial Bodies in Inclined Orbits

The Astrophysical Journal
Through the Rossiter–McLaughlin effect, several hot Jupiters have been found to exhibit spin–orbit misalignment and even retrograde orbits. The high obliquity observed in these planets can be attributed to two primary formation mechanisms, as summarized ...

Fe Atoms Accelerator Coupled With Oxygen Vacancies Channel Synergistically Boost OER Performance of Fe‐CoMoO4‐Ov Nanosheets

Carbon Energy, EarlyView.
Fe‐CoMoO4‐Ov/NF demonstrates significantly improved OER catalytic performance compared to CoMoO4. Specifically, the introduced Fe atoms act as a promoter for surface reconstruction, significantly reducing the energy required for surface reconstruction to generate FeCoOOH. The oxygen vacancies serve as electron channels between the core Fe‐CoMoO4‐Ov and

Influence of Solar Wind Parameters on Pickup Ion Beam Instabilities Upstream of Mars: Linear Analysis

The Astrophysical Journal
Linear instability analysis is performed to investigate the influence of solar wind parameters on instabilities driven by a cool pickup ion beam distribution, which is believed to excite the proton cyclotron waves upstream of Mars.

The Rich Chemistry of Ionized Methanol With Sulfur Dioxide: Pathways to Prebiotic and Elusive Species in Earth's Atmosphere and Space

Chemistry – A European Journal, EarlyView.
The reaction between the methanol radical cation and sulfur dioxide is remarkably fast and forms several ionic and neutral products (HOSOH+, CH2OSO+, CH2OH+, CH2O, H2O, HSO2). The chemistry goes beyond simple proton or hydrogen transfer, revealing a close interaction between the two species, relevant to atmospheric and astrochemical environments where ...

Two dimensional hybrid simulations of small scale obstacles in the solar wind [PDF]

The structure and dynamics of the solar wind interaction with two small scale obstacles (of the order of a pickup ion gyroradius) is examined. These are a comet, comparable to Grigg-Skjellerup, and a weakly ionospheric planet.

Uncatalyzed Guanosine Phosphorylation under Potentially Prebiotic Conditions

Chemistry – A European Journal, EarlyView.
Pyrophosphate acts as phosphorylating agent of guanosine under simple wet‐dry cycles without condensing agent and inorganic catalysts to afford cyclic guanosine monophosphate derivatives useful for oligomerization in prebiotic processes. ABSTRACT The phosphorylation of nucleosides and their subsequent polymerization are key issues in the study of the ...

S/W Development of High Precesion EPHEMERIS(I) [PDF]

Journal of Astronomy and Space Sciences, 1993
We developed the S/W which calculate the Planetary and the Moon ephemerides. The ephemeris of the Solar system objects was obtained from a simultaneous numerical integration of the equations of motion for the nine planets and the Moon.

The Role of Business R&D in Environmental Sustainability: Evidence From the Nordic Countries

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT As environmental sustainability becomes an increasingly important concern for advanced economies, the role of business innovation in relation to environmental outcomes has attracted increasing attention. This study examines the relationship between business enterprise research and development (BERD) and environmental sustainability in the ...

Mirror-mode Structures in Coronal Mass Ejection Sheaths

The Astrophysical Journal
Coronal mass ejections (CMEs) compress the upstream solar wind as they travel through interplanetary space, forming sheath regions and preceding shocks rich in plasma dynamics.

A Fast and Highly Stable Aqueous Calcium‐Ion Battery for Sustainable Energy Storage

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
Aqueous batteries provide a low‐cost, safer alternative to lithium‐ion batteries, but their viability is often limited by rapid electrode degradation. This study shows that replacing K+ with divalent Ca2+ ions in the electrolyte significantly boosts the stability of both copper hexacyanoferrate cathodes and polyimide anodes, enabling fast‐charging ...
