Query: Rotating Hybrid Stars with Color-Flavor-Locked Quark Matter   In the present work we have achieved phase transition from $\beta$ stable
hadronic matter to color-flavor locked (CFL) quark matter with Maxwell
construction. The hybrid equation of state (EoS), obtained for different values
of bag pressure $B$ and gap parameter $\Delta$, have been used to compute the
speed of sound in hybrid star (HS) matter. The structural properties of the HSs
in both static and rotating conditions have been calculated in the light of
various constraints from different astrophysical and empirical perspectives.
The effects of $B$ and $\Delta$ on the EoS and structural properties have been
investigated. At a certain density, shortly after phase transition, the HSs
become unstable. In static conditions, the mass-radius solutions satisfy the
constraints from GW190425, NICER experiment for PSR J0030+0451 and PSR
J0740+6620 and from massive pulsars like PSR J0348+0432 and PSR J0740+6620. In
rapidly rotating conditions at Kepler frequency, the constraints on maximum
mass from the secondary component of GW190814 and that on rotational frequency
from fast pulsars like PSR B1937+21 and PSR J1748-2446ad are all satisfied. In
slowly rotating conditions, the universality relations in terms of normalized
moment of inertia also hold quite well for most of our HS configurations.
