Ephemeris and Celestial Navigation. Melville’s Mardi as Astronomical Metaphor

open access: yesMiranda: Revue Pluridisciplinaire du Monde Anglophone, 2022
Melville as a sailor expressed his fascination for astronomy, ephemerides and their creative potential, which is evidenced in the metaphorical setting that structures the whole argument of Mardi ’s confusing world.

Korean Historical Records on Halley’s Comet Revisited [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2014
In this paper, we report the analysis of Korean historical records on the periodic Halley’s comet according to the period (i.e., the Three Kingdoms, Goryeo Dynasty, and Joseon Dynasty) using various sources such as the Samguksagi (The History of the ...

Propagation of nonlinear waves in multi-component pair plasmas and electron–positron–ion plasmas

open access: yesAIP Advances, 2022
The propagation of small amplitude stationary profile nonlinear solitary waves in a pair plasma is investigated by employing the reductive perturbation technique via the well-known Korteweg–de Vries (KdV) and modified KdV (mKdV) equations.

Solitary and shocklike wave solutions for the Gardner equation in dusty plasmas

open access: yesJournal of Taibah University for Science, 2020
The propagation of dust ion acoustic waves (DIAWs) for two-temperature ions with isothermal electrons in dusty plasmas has been investigated. Using the reductive perturbation method, the Gardner equation is derived.

Comet dust as a mixture of aggregates and solid particles: model consistent with ground-based and space-mission results [PDF]

open access: yes, 2009
The most successful model of comet dust presents comet particles as aggregates of submicron grains. It qualitatively explains the spectral and angular change in the comet brightness and polarization and is consistent with the thermal infrared data and ...

Symplectic map description of Halley's comet dynamics [PDF]

open access: yes, 2014
We determine the two-dimensional symplectic map describing 1P/Halley chaotic dynamics. We compute the Solar system kick function, i.e. the energy transfer to 1P/Halley along one passage through the Solar system.

Local manifestations of cometary activity [PDF]

open access: yes, 2019
Comets are made of volatile and refractory material and naturally experience various degrees of sublimation as they orbit around the Sun. This gas release, accompanied by dust, represents what is traditionally described as activity.
