Abstract:
CD photometric observations in VRI colours and spectroscopic
observations of the newly discovered eclipsing binary GSC 2314-0530
(NSVS 6550671) 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 GSC 2314-0530: T1=3735K; T2=3106K; M1=0.51M☉;
M2=0.26M☉; R1=0.55R☉; R2=0.29R☉; L1=0.053L☉;
L2=0.007L☉; i=72.5{swg}; a=1.28R☉; d=59pc.
Description:
The CCD photometry of GSC 2314-0530 in the VRI bands was carried out
at Rozhen National Astronomical Observatory with the 2-m RCC telescope
equipped with a VersArray1 CCD camera (1300x1340 pixels, 20-um pixel,
field of 5.25x5.35 arcmin) as well as with the 60-cm Cassegrain
telescope using the FLI2 PL09000 CCD camera (3056x3056 pixels, 12-um
pixel, field of 17.1x17.1 arcmin), between 2009 July 25 and Dec 30.
