Thermodynamic constraints on the citric acid cycle and related reactions in ocean world interiors
Seda Işık, Mohit Melwani Daswani, Emre Işık +2
Icy ocean worlds attract significant interest for their astrobiological potential due to subsurface oceans, organics, and chemical energy sources. We quantify thermodynamic viabili…
Temporal and Periodic Variation of the MCMESI for the Last Two Solar Cycles; Comparison with the Number of Different Class X-Ray Solar Flares
A. Kilcik, P. Chowdhury, V. Sarp +4
In this study we compared the temporal and periodic variations of the Maximum CME Speed Index (MCMESI) and the number of different class (C, M, and X) solar X-Ray flares for the la…
Physical Characteristics of Umbral Dots Derived from a High Resolution Observation
Ali Kilcik, Volkan Sarp, Vasyl Yurchyshyn +2
The aim of this study is revisit the physical parameters of umbral dots (UDs) with the latest high resolution observations and contribute to the scientific understanding of their f…
Recent advances in the monodromy theory of integrable Hamiltonian systems
Nikolay Martynchuk, Henk W. Broer, Konstantinos Efstathiou
The notion of monodromy was introduced by J. J. Duistermaat as the first obstruction to the existence of global action coordinates in integrable Hamiltonian systems. This invariant…
Sunspot group tilt angles from drawings for cycles 19-24
Emre Isik, Seda Isik, Bahar B. Kabasakal
The tilt angle of a sunspot group is a critical quantity in the surface transport of magnetic flux and the solar dynamo. To contribute long-term databases of the tilt angle, we dev…
Critical frequencies of the ionospheric and layers during the last four solar cycles: sunspot group type dependencies
Erdal Yiğit, Ali Kilcik, Ana Georgina Elias +4
The long term solar activity dependencies of ionospheric F and F regions' critical frequencies ( and ) are analyzed for the last four solar cycles (1976--20…
