Abstract:
In this paper, we present the results of a detailed spectroscopic
and photometric analysis of the V=13.4mag low-mass eclipsing binary
NSVS 06507557 with an orbital period of 0.515d. We have obtained a
series of mid-resolution spectra covering nearly the entire orbit of
the system. In addition, we have obtained simultaneous VRI broad-band
photometry using a small aperture telescope. From these spectroscopic
and photometric data, we have derived the system's orbital parameters
and we have determined the fundamental stellar parameters of the two
components. Our results indicate that NSVS 06507557 consists of a K9
pre-main-sequence star and an M3 pre-main-sequence star.
Description:
he photometric observations of NSVS 0650 were carried out with the
0.4-m telescope at the Ege University Observatory. The 0.4-m telescope
is equipped with an Apogee 1kx1k CCD camera and standard Bessel VRI
bandpasses. The observations were performed over seven nights between
2008 September 1 and November 30.
