GSC2314-0530: the shortest-period eclipsing system with dMe components.

DIMITROV D.P. and KJURKCHIEVA D.P.

Abstract (from CDS):

CCD photometric observations in VRI colours and spectroscopic observations of the newly discovered eclipsing binary GSC2314-0530 (NSVS6550671) with dMe components and a very short period of P = 0.192636d are presented. The simultaneous light-curve solution and radial velocity solution allow us to determine the global parameters of GSC2314-0530: T1= 3735K; T2= 3106K; pc. The chromospheric activity of its components is revealed by strong emission in the Hα line (with mean EW = 5Å) and several observed flares. Empirical relations for mass-, mass-radius and mass-temperature are derived on the basis of the parameters of known binaries with low-mass dM components.
