Abstract:
Eclipsing binaries provide a unique opportunity to measure fundamental
properties of stars. With the advent of all-sky surveys, thousands of
eclipsing binaries have been reported, yet their light curves are not
fully exploited. The goal of this work is to make use of the eclipsing
binary light curves delivered by all-sky surveys. We attempt to
extract physical parameters of the binary systems from their light
curves and colour. Inspired by the work of Devor et al., we use the
Detached Eclipsing Binary Light curve fitter (DEBIL) and the Method
for Eclipsing Component Identification (MECI) to derive basic
properties of the binary systems reported by the All Sky Automated
Survey, the Northern Sky Variability Survey, and the Lincoln Near
Earth Asteroids Research. We derive the mass, fractional radius, and
age for 783 binary systems. We report a subsample of eccentric systems
and compare their properties to the tidal circularization theory. With
MECI, we are able to estimate the distance of the eclipsing binary
systems and use them to probe the structure of the Milky Way.
Following the approach of Devor et al., we demonstrate that DEBIL and
MECI are instrumental to investigate eclipsing binary light curves in
the era of all-sky surveys, and provide estimates of stellar
parameters of both binary components without spectroscopic
information.
Description:
We follow the approach of Devor et al. (2008AJ....135..850D 2008AJ....135..850D, Cat.
J/AJ/135/850) to analyse the LC from ASAS (Pojmanski et al., Cat.
II/264, NSVS (Wozniak et al., 2004AJ....127.2436W 2004AJ....127.2436W, and LINEAR
(Palaversa et al., Cat. J/AJ/146/101) and extract the physical
properties of the eclipsing binaries.

Note (1): Please note that when the most likely model is at the edge of the
parameter space, MECI will not be able to bound the solution, hence cannot
estimate the uncertainties. Limat flag parameter as follows:
-3 = when MECI reaches the upper limit
-2 = when it reaches the lower limit
-1 = if the parameter is at its limit
