On Equilibrium Figures of Particle Clouds around the Sun and Stars

open access: yesOpen Astronomy, 2015
Equilibrium figures of cold gas-dust (or cometary) clouds are studied in a more general setting than the classical Roche problem. The cloud is considered to be under the influence of gravitational attraction of the central star and the tidal field of the

A MODIFICATION OF GAUSS' METHOD FOR PRELIMINARY DETERMINATION OF A CELESTIAL BODY'S ORBIT

open access: yesOdessa Astronomical Publications, 2016
A modification of classical Gauss’ method for determination of Keplerian elements from the observed positions is considered in this paper. The modification involves the exhaustive enumeration of all possible orbital plane positions in order to improve ...

Melnikov method for autonomous Hamiltonians

open access: yes, 1996
The web page contains both the dvi and postscript version of the paper. This paper presents the method of applying the Melnikov method to autonomous Hamiltonian systems in dimension four. Besides giving an application to Celestial Mechanics, it discusses

From Everyman to Hamlet: A Distant Reading

open access: yesRenaissance Studies, EarlyView.
Abstract The sixteenth century sees English drama move from Everyman to Hamlet: from religious to secular subject matter and from personified abstractions to characters bearing proper names. Most modern scholarship has explained this transformation in terms originating in the work of Jacob Burckhardt: concern with religion and a taste for ...

The Unreasonable Effectiveness of the nΣv Approximation

open access: yesThe Astrophysical Journal
In kinetic theory, the classic n Σ v approach calculates the rate of particle interactions from local quantities: the number density of particles n , the cross section Σ, and the average relative speed v .

Time Tools

open access: yesTopics in Cognitive Science, EarlyView.
Abstract Many core human activities require an understanding of time. To coordinate rituals, plan harvests and hunts, recall histories, keep appointments, and follow recipes, we need to grapple with invisible temporal structures like durations, sequences, and cycles. No other species seems to do this.

Good rotations

open access: yes, 1998
Numerical integrations in celestial mechanics often involve the repeated computation of a rotation with a constant angle. A direct evaluation of these rotations yields a linear drift of the distance to the origin.
