Photometric and Spectroscopic Analysis of Eclipsing Binary NSVS 11868841.

Abstract (from CDS):

We present new photometric and spectroscopic data on the low-mass, eclipsing binary star NSVS 11868841. Light and velocity data are analyzed and modeled. Resulting best-fit models indicate a change in the orbital period. Our 2019 October observation of secondary eclipse occurs 0.01042 days prior to that predicted by the latest published ephemeris when assuming a circular orbit. Our spectroscopic data from 2009 and 2019 yield a consistent systemic velocity of -9.78 ± 1.3 km s–1 and a mass ratio of 0.928 ± 0.016, both of which are significantly different than previous studies. Orbital period changes have not been indicated in earlier works either.
