A philosophical history of infinitesimals
Vladimir Kanovei, Mikhail G. Katz, Taras Kudryk +1
We explore the issue of providing a foundational framework for Leibnizian infinitesimals in the light of modern standard and nonstandard approaches. We outline a trichotomy of ordi…
Ukrainian Wartime Astronomy and its Prospects
Danilo Albergaria, Kateryna Frantseva, Pedro Russo +20
The Russian invasion of Ukraine damaged or compromised astronomical facilities and has prompted the displacement of researchers. A plan to restore Ukrainian astronomy, rooted in a…
The HADS Star CSS_J102714.3+205943: a Component of a Binary System with an Elliptic Orbit?
Maksym Yu. Pyatnytskyy, Ivan L. Andronov
We analyzed period changes of the high-amplitude Delta Scuti variable star CSS_J102714.3+205943 for about 20 years, utilizing data from the automated sky surveys along with our own…
The MAGIC project. III. Radial and azimuthal Galactic abundance gradients using classical Cepheids
V. Kovtyukh, B. Lemasle, G. Bono +7
Radial abundance gradients provide sound constraints for chemo-dynamical models of galaxies. Azimuthal variations of abundance ratios are solid diagnostics to understand their chem…
Tetralin + fullerene C60 solutions for thermal management of flat-plate photovoltaic/thermal collector
Rita Adrião Lamosa, Igor Motovoy, Nikita Khliiev +8
A new composite heat transfer fluid consisting of tetralin and fullerene has been proposed for photovoltaic thermal hybrid solar harvesting. It features a unique absorption spectru…
Mathematical Modelling of Astrophysical Objects and Processes
Ivan L. Andronov, Vitalii V. Breus, Larysa S. Kudashkina
In this review, we present some advanced algorithms and programs used in our scientific school with short description of types of astrophysical systems, which we study. However, we…
