Competition of Short-Range and Long-Range Mechanisms of Spectral Line Broadening in Emission of Atomic and Molecular Gases

Smirnov, B. M.

An analogy is shown for broadening the spectral line of atoms in the case of competition between the short-range Doppler broadening mechanism and the long-range impact mechanism in atomic gases, as well as for the absorption band of a molecular gas in the infrared (IR) region of the spectrum, where the longrange part of the spectrum is also determ…

Wavelet analysis of fine-scale structures in the Saturnian B and C rings using data from the Cassini spacecraft

Postnikov, E. B.; Loskutov, A. Yu.

A continuous wavelet transform with a complex Morlet basis offers an effective method for the analysis of an instant variable periodicity in the spatially inhomogeneous matter density in the radial structure of Saturn’s rings. An original algorithm that reduces the integral transform to solving a Cauchy problem for a partial differential equation …
