Query: Eclipsing binary stars in the Large Magellanic Cloud. Results from the
  EROS-2, OGLE and VMC surveys   We present a catalogue of 1768 eclipsing binary stars (EBs) detected in the
Large Magellanic Cloud (LMC) by the second generation of the EROS survey
(hereinafter EROS-2); 493 of them are new discoveries located in outer regions
(out of the central bar) of the LMC. These sources were originally included in
a list of candidate classical Cepheids (CCs) extracted from the EROS-2
catalogue on the basis of the period (0.89 $<P_{EROS}<$15.85 days) versus
luminosity ($13.39 < \langle B_{EROS}\rangle<17.82$ mag) diagram. After visual
inspection of the light curves we reclassified them as eclipsing binaries. They
have blue colours ($B_{EROS} - R_{EROS} < $ 0.2 mag) hence we classed them as
hot eclipsing binaries (HEBs) containing hot massive components: main sequence
(MS) stars or blue giants. We present $K_{\rm s}$-band light curves for 999
binaries from our sample that have a counterpart in the VISTA near-infrared ESO
public survey of the Magellanic Clouds system (VMC). We provide spectral
classifications of 13 HEBs with existing spectroscopy. We divided our sample
into contact-like binaries and detached/semi-detached systems based on both
visual inspection and the parameters of the Fourier decomposition of the light
curves and analysed the period-luminosity ($PL$) relations of the contact-like
systems using the $R_{EROS}$ and $K_{\rm s}$ magnitudes at maximum light. The
contact-like binaries in our sample do not follow $PL$ relations. We analysed
the sample of contact binaries from the OGLE III catalogue and confirmed that
$PL_I$ and $PL_{K_{\rm s}}$ sequences are defined only by eclipsing binaries
containing a red giant component.
