Query: Hybrid stars in the light of GW170817   We have studied the effect of tidal deformability constraint given by the
binary neutron star merger event GW170817 on the equations of state (EOS) of
hybrid stars. The EOS are constructed by matching the hadronic EOS described by
relativistic mean field (RMF) model and parameter sets NL3, TM1 and
NL3$\omega\rho$ with the quark matter EOS described by modified MIT bag model,
via Gibbs' construction. It is found that the tidal deformability constraints
along with the lower bound on maximum mass ($M_{\rm max}=2.01\pm0.04M_\odot$)
significantly limit the bag model parameter space ($B_{\rm eff}^{1/4}$, $a_4$).
We also obtain upper limits on the radius of $1.4M_\odot$ and $1.6M_\odot$
stars as $R_{1.4}\leq13.2-13.5$ km and $R_{1.6}\leq13.2-13.4$ km, respectively
for different hadronic EOS considered here.
