INTER-LONGITUDE ASTRONOMY PROJECT: SOME RESULTS AND PERSPECTIVES

The highlights of the recent study of variable stars of different types are discussed. We present some results (out of more than 500 papers) and plans for the further studies within bi- or multi-lateral observational campaigns. Special attention is paid to the polarimetric and photometric monitoring of polars, intermediate polars, superhumpers in dwarf novae and nova-like systems, symbiotic variables, pulsating semi-regular and Mira-type stars and other long-periodic variables, new suspected variables from the Hipparcos-Tycho space observatory and other surveys. To study multi-periodic and aperiodic variability superimposed onto long-term trends, an expert system for time series analysis is briefly referred.
