We present an application of the methods recently developed for thestudy of quasicrystal structures to the analysis of multiperiodicity of semiregularvariables.
The Antarctic Continent has become the largest natural preservatory of meteorites in the world because of its unique geographical position and climatic conditio
In previous works, a generic dynamical model has been suggested byHuang et al., which is shown to be correct for both adiabatic and radiative blast-waves, in bo
Quasi-simultaneous VLBI observations at 15-86 GHz have shown that in the classical superhluminal radio source 3C 273, the spectral index α (Sν oc να)has a s
Complete BV light curves of the W UMa type binary RT LMi are presented. From the observations, four times of minimum light were determined.Based on the new time
