Simulation of the Motion of Stars Escaping from the Galactic Center

Open Astronomy, 2015
Motions of stars escaping from the Galactic center are simulated. It is shown that the Galactic bar reduces the initial velocity needed to escape from the Galaxy.

On the integrability of the n-centre problem

, 2004
It is known that for $n \geq 3$ centres and positive energies the $n$-centre problem of celestial mechanics leads to a flow with a strange repellor and positive topological entropy.

From Everyman to Hamlet: A Distant Reading

Renaissance 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 ...

Collisional Velocities and Rates in Resonant Planetesimal Belts

, 2007
We consider a belt of small bodies around a star, captured in one of the external or 1:1 mean-motion resonances with a massive perturber. The objects in the belt collide with each other.

Invariant manifolds, discrete mechanics, and trajectory design for a mission to Titan [PDF]

, 2009
With an environment comparable to that of primordial Earth, a surface strewn with liquid hydrocarbon lakes, and an atmosphere denser than that of any other moon in the solar system, Saturn's largest moon Titan is a treasure trove of potential scientific ...

Good rotations

, 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.

Computers in Our Cosmos: Intersections in Geographies of Care, Abolition Geographies and Worker Movements

Transactions of the Institute of British Geographers, EarlyView.
ABSTRACT AI assistants on spacecrafts. Netflix streamed through inter‐planetary communication networks. Colonies on Mars by 2050. While the glamorous public–private ventures into outer space curate discussions on the technical specificities of these proposed projects, this paper reorients discussions on such developments through critical frameworks of ...
