Compressibility Function and Speed of Sound in the Non‐Commutative Quantum Hadrodynamics Type‐I Model for Neutron Stars

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT We investigate the effects of a minimal measurable length on neutron stars, within the quantum hadrodynamics (QHD‐I) model modified by the Generalized Uncertainty Principle (GUP). Working in a deformed Poisson algebra framework, we incorporate GUP effects via a time‐invariant transformation of the phase space volume, effectively reducing the ...

A Review of Astronomy Education Research

open access: yesAstronomy Education Review, 2003
The field of astronomy education is rapidly growing beyond merely sharing effective activities or curriculum ideas. This paper categorizes and summarizes the literature in astronomy education research and contains more than 100 references to articles, books, and Web-based materials.

New Arabic Records From Cairo on Supernovae 1181 and 1006

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT The remnant of the historical supernova SN 1181 is under discussion: While the previously suggested G130.7+3.1 (3C58) appears too old (3000–5000 year), the unusual star IRAS00500+6713 with a surrounding nebula (Pa‐30) has an expansion age not inconsistent with a SN Iax explosion in ad 1181 under the assumption that neither acceleration nor ...

eChem: Accelerated Method Development in Quantum Chemistry with Notebooks

open access: yesChemistry–Methods, EarlyView.
The benefits of using Jupyter Notebooks to simplify and accelerate scientific code development are demonstrated using the practical example of the analytical molecular Hessian. The eChem project has been previously presented as an interactive platform for quantum and computational chemistry education [J. Chem. Educ. 100, 1664–1671].

UV–Vis Spectra of Carbonic Acid: Rationalizing Experimental Redshifts between Monomer and Bulk based on (H2CO3)n Calculations

open access: yesChemPhysChem, EarlyView.
In bulk carbonic acid (e.g., in interstellar icy dust grains) cluster formation produces two distinct UV‐Vis spectral features redshifted by ≈2 eV (25 nm) and by ≈5 eV (80 nm) compared to gas phase single molecule carbonic acid 's adiabatic ionization energy. Theory and experiment were used to investigate the origin of these shifts.

The Lock‐In Effect on ESG and Business Performance Relationship: A Critical Examination and Meta‐Analysis

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study investigates whether the issues previously addressed in the literature regarding business performance persist when applying ESG practices. A literature review identified 252 effects, followed by a meta‐analysis with subgroup analysis. The lock‐in theory and corporate reputation were employed to understand this relationship. The lock‐
