摘要
The obtained optical (V and I) photometry of several known brown dwarfs (BDs) demonstrates the possibility for observations of BDs with the telescopes at Rozhen NAO. Criteria for searching for brown-dwarf candidates are derived on the base of statistical analysis. Observations of three arbitrary sky fields and applying of the selection criteria lead to finding of 14 BD candidates. Their spectral types are predicted on the base of the established statistical relations.
