Scientific paper
The nearby M dwarf Gliese 570B has been spatially resolved in two components by infrared speckle interferometric observations. In the meantime, it was followed as a spectroscopic binary. By combination of four interferometric observations and the previously determined orbital parameters of the SB2 system, we derive the full set of parameters and estimations for the masses of the components.
