Quasi-Normal Modes of Stars and Black Holes [PDF]
Perturbations of stars and black holes have been one of the main topics of relativistic astrophysics for the last few decades. They are of particular importance today, because of their relevance to gravitational wave astronomy.

On New Modifications of Some Perturbation Procedures
In this paper, we present new modifications for some perturbation procedures used in mathematics, physics, astronomy, and engineering. These modifications will help us to solve the previous problems in different sciences under new conditions. As problems,

XXII. An improved solution of a problem in physical astronomy; by which, swiftly converging series are obtained, which are useful in computing the perturbations of the motions of the Earth, Mars, and Venus, by their mutual attraction. To which is added an appendix, containing an easy method of obtaining the sums of many slowly converging series which arise in taking the fluents of binominal surds, &c. In a letter to the Rev. Nevil Maskelyne, D. D. F. R. S. and Astronomer Royal [PDF]
Reverend Sir, Such is the subject of the inclosed paper, and such the reputation for skill and industry, which the many valuable papers you have communicated to the Royal Society, and your other learned works, have justly procured to you, that it could not with more propriety be submitted to the judgment of any other person than yourself,

Close Binary Stars Modeled by Two Prolate Ellipsoids in Synchronous Rotation
The presence of tidal deformations in close binary stars has already been confirmed by astronomical observations. The present paper aims to simply address an astronomy problem, studying the relative movement of close binaries disturbed by their mutual ...

Leonhardi Euleri Opera omnia: Editing the works and correspondence of Leonhard Euler [PDF]
The paper gives an overview on the history and present state of the edition of the complete works of Leonhard Euler (1707–1783). After several failed initiatives in the 19th century, the project began in 1907 with the edition of Euler’s printed works ...

Rotochemical Heating of Neutron Stars: Rigorous Formalism with Electrostatic Potential Perturbations [PDF]
The electrostatic potential that keeps approximate charge neutrality in neutron star matter is self-consistently introduced into the formalism for rotochemical heating presented in a previous paper by Fernandez and Reisenegger. Although the new formalism is more rigorous, we show that its observable consequences are indistinguishable from those of the ...

One-dimensional, surface emitting, disordered Terahertz lasers
Quantum cascade lasers are, by far, the most compact, powerful, and spectrally pure sources of radiation at terahertz frequencies, and, as such, they are of crucial importance for applications in metrology, spectroscopy, imaging, and astronomy, among ...

Fast Magnetosonic Waves Driven by Gravitational Waves [PDF]
The propagation of a gravitational wave (GW) through a magnetized plasma is considered. In particular, we study the excitation of fast magnetosonic waves (MSW) by a gravitational wave, using the linearized general-relativistic hydromagnetic equations. We
