We present the catalog of RR Lyrae stars discovered in a 4.5 square degrees area in the central parts of the Large Magellanic Cloud (LMC). Presented sample contains 7612 objects, including 5455 fundamental mode pulsators (RRab), 1655 first-overtone (RRc), 272 second-overtone (RRe) and 230 double-mode RR Lyr stars (RRd). Additionally we attach a list of several dozen other short-period pulsating variables. The catalog data include astrometry, periods, BVI photometry, amplitudes, and parameters… 
Discrete Scale Relativity and SX Phoenicis Variable Stars
Discrete Scale Relativity proposes a new symmetry principle called discrete cosmological self-similarity which relates each class of systems and phenomena on a given Scale of nature’s discrete
Discrete Self-Similarity between RR Lyrae Stars and Singly-Excited Helium Atoms
Classical variable stars called RR Lyrae stars have pulsating outer envelopes constituted of excited atoms. Here we demonstrate that the qualitative and quantitative properties of RR Lyrae variables
Introduction of Empirical Topology in Construction of Relationship Networks of Informative Objects
This work proposes a method for discovering relationships between individuals (single or groups) that is based on what it calls the empirical topology, a system-theoretic measure of functional proximity and applies it to an astronomical data base.
