Query: Constraining Bag constant for Hybrid Neutron stars   We study the star matter properties for Hybrid equation of state (EoS) by
varying the bag constant. We use the Effective-Field-Theory motivated
Relativistic Mean-Field model (E-RMF) for hadron phase with recently reported
FSUGarnet, G3 and IOPB-I parameter sets. The result of NL3 and NL3${\omega
\rho}$ sets are also shown for comparison. The simple MIT Bag model is applied
for the quark phase to construct the hybrid EoS. The hybrid neutron star mass
and radius are calculated by varying with $B^{1/4}$ to constrain the $B^{1/4}$
values. It is found that $B^{1/4}$=130-160 MeV is suitable for explaining the
quark matter in neutron stars.
