... Stars . ... Cepheid variable stars have been known since the 18th century. ... Regularly brightening to a peak over days, weeks or months before fading these variable stars were remarkable curiosities to astronomers in past centuries.€а The term Cepheid is taken from the star Delta Cephei in the constellation of Cepheus, which was identified as variable€а in 1784 by the teenaged prodigy John Goodricke (1764-96). ...

... In order to describe the effect of distortion of the trajectory of an electromagnetic wave in atmosphere, it is needed to use the solution of the dispersion equation of moving medium electrodynamics for the spatial case of atmosphere motion. The solution of the dispersion relation for the propagation of an electromagnetic wave in a medium is valid for an atomic layer with a thickness on the order of a few wavelengths of the electromagnetic radiation. ...

We present a catalogue of galaxies for which spatially resolved data on their internal kinematics have been published; there is no apriori restriction regarding their morphological type. The catalogue lists the references to the articles where the data are published, as well as a coded description of these data: observed emission (E) or absorption (A) data, optical (O) or radio (R) data, velocity (V) or velocity dispersion (D), radial profile (1) or 2D field (2). ...
