Abstract In the last decade, over 7000 eclipsing binaries have been discovered in the Local Group through various variability surveys. Measuring fundamental parameters of these eclipsing binaries has become feasible with 8 meter class telescopes, making it possible to use eclipsing binaries as distance indicators. Distances with eclipsing binaries provide an independent method for calibrating the extragalactic distance scale and thus determining the Hubble constant. This method has been used… 
Discovery and characterization of detached M dwarf eclipsing binaries in the WFCAM Transit Survey
We report the discovery of 16 detached M-dwarf eclipsing binaries with J < 16 mag and provide a detailed characterisation of three of them, using high-precision infrared light curves from the WFCAM
Into the Starry Gulfs
Among the many stars that are known to vary in brightness are the eclipsing binaries – pairs of stars that orbit each other, causing each component to pass in front of the other as seen from Earth.
A catalog of new eclipsing binaries in the Kepler database
In this thesis, we present a catalog of binary stars discovered in the publicly available Kepler database, none of which were included in previous such catalogs published by the Kepler science team.
The effect of phased recurrent units in the classification of multiple catalogs of astronomical lightcurves
TLDR
This work uses seven catalogs containing periodic and nonperiodic astronomical objects and shows that LSTM outperformed PLSTM on 6/7 datasets and the combination of both units enhances the results in all datasets.

Photometric Solutions for Semidetached Eclipsing Binaries: Selection of Distance Indicators in the Small Magellanic Cloud
Estimation of distances to nearby galaxies by the use of eclipsing binaries as standard candles has recently become feasible because of new large-scale instruments and the discovery of thousands of
Ten eclipsing binaries in the Small Magellanic Cloud: fundamental parameters and SMC distance
We present the first results of an observational programme to measure the fundamental parameters of over 100 eclipsing binaries in the Small Magellanic Cloud (SMC). The spectroscopic data were
DIRECT Distances to Nearby Galaxies Using Detached Eclipsing Binaries and Cepheids. VI. Variables in the Central Part of M33
The DIRECT project aims to determine direct distances to two important galaxies in the cosmological distance ladder—M31 and M33—using detached eclipsing binaries (DEBs) and Cepheids. We present the
DIRECT Distances to Nearby Galaxies Using Detached Eclipsing Binaries and Cepheids. IX. Variables in the Field M31Y Discovered with Image Subtraction
The DIRECT Project aims to obtain direct distances to two Local Group galaxies, M31 and M33, which occupy a crucial position near the base of the cosmological distance ladder. The first step is to
The MOA catalogue of eclipsing binary stars in the Small Magellanic Cloud
We present a catalogue of 167 eclipsing binary stars in the Small Magellanic Cloud (SMC) derived from the data base of time-series photometry for 400 000 SMC stars acquired by the Microlensing
DIRECT Distances to Nearby Galaxies Using Detached Eclipsing Binaries and Cepheids. II. Variables in the Field M31A
We have undertaken a long-term project, DIRECT, to obtain the direct distances to two important galaxies in the cosmological distance ladder—M31 and M33—using detached eclipsing binaries (DEBs) and
First Determination of the Distance and Fundamental Properties of an Eclipsing Binary in the Andromeda Galaxy
We present the first detailed spectroscopic and photometric analysis of an eclipsing binary in the Andromeda Galaxy (M31). This is a 19.3 mag semidetached system with late O and early B spectral type
Fundamental Properties and Distances of Large Magellanic Cloud Eclipsing Binaries. III. EROS 1044
We present results from a detailed analysis of a third eclipsing binary (EB) system in the Large Magellanic Cloud, EROS 1044 (~B2 IV-V + ~B2 III-IV). Our study combines the "classical" EB study of
The extragalactic distance scale
Significant progress has been made during the last 10 years toward resolving the debate over the expansion rate of the Universe. The current value of the Hubble parameter, H0, is now arguably known
Variable Stars in the Large Magellanic Cloud: Discovery of Extragalactic W UMa Binaries*
We observed a field in the disk of the LMC on two consecutive nights in search of rapid variable stars. We found two pulsating stars of type RRab and δ Scuti and four binary stars; among the latter
