Abstract
We report the results of our optical speckle interferometric observations of the nearby triple system GJ 795 performed with the 6 m telescope of the Special Astrophysical Observatory of the Russian Academy of Sciences with diffraction-limited angular resolution. The three components of the system were optically resolved for the first time. Position measurements allowed us to determine the elements of the inner orbit of the triple system. We use the measured magnitude differences to estimate the absolute magnitudes and spectral types of the components of the triple: M Aa V =7.31±0.08, M Ab V =8.66±0.10, M B V =8.42±0.10, Sp Aa≈K5, Sp Ab≈K9, Sp B ≈K8. The total mass of the system is equal to ΣM AB =1.69±0.27M ⊙. We show GJ795 to be a hierarchical triple system which satisfies the empirical stability criteria.
