The influence of merging effects in the central part of an Active Galactic Nucleus (AGN) on the emission spectral line shapes are discussed. We present a model of close binary Broad Line Region. The numerical experiments show that the merging effects can explain double peaked lines. The merging effects may also be present in the center of AGNs

Over the last two decades, many efforts have been devoted to the search for brown dwarfs, and various ways of finding them have been developed. Deep photometric surveys in nearby open clusters is one approach that has provided a large amount of candidates. These clusters offer a number of advantages (a single known distance, metallicity and age)
