Observations and analysis of MT Her

Previously reportedBV photometry of MT Her is analysed with the aid of efficient curve-fitting techniques. There is insufficient overall data to allow a definitive parametrization of the binary, but we can confidently rule out the possibility of a classical Algol.A provisional model is advanced which consists of two close unevolved dwarfs: the primary a late F-type and the secondary a mid K-type. The system is located at a distance of about 250 pc in a region of fairly heavy interstellar extinction near the galactic disk. It may be a short-period RS CVn-type binary, but this possibility, as the provisional model itself, requires spectrographic confirmation.
