Abstract

The multi-color photometric and spectroscopic (based on observations obtained with the T{Ü}B{İ}TAK National Observatory 1.5-meter telescope, which is owned and operated by the T{Ü}B{İ}TAK) observations of the newly discovered eclipsing binary NSVS 07394765 were obtained. The resultant light and radial velocities were analysed and the global parameters of the system: T $_{1}$ =3 300 K; T $_{2}$ =3 106 K; M $_{1}$ =0.36 M $_{⊙}$ ; M $_{2}$ =0.18 M $_{⊙}$ ; R $_{1}$ =0.46 R $_{⊙}$ ; R $_{2}$ =0.50 R $_{⊙}$ ; L $_{1}$ =0.030 L $_{⊙}$ ; L $_{2}$ =0.026 L $_{⊙}$ ; $i = 89.2^{\circ}$ ; $a = 5.97$ R $_{⊙}$ ; $d = 28$ pc. The chromospheric activity of its components is revealed by strong emission in the H $α$ line and observed flares. Empirical relations for mass-radius and mass-temperature are derived on the basis of the parameters of known binaries with low-mass dM components.
