Starting from equations of state of nucleonic and color-superconducting quark matter and assuming a first-order phase transition between these , we construct an equation of state of stellar matter , which contains three phases : a nucleonic phase , as well as two-flavor and three-flavor color-superconducting phases of quarks .
Static sequences of the corresponding hybrid stars include massive members with masses of \sim 2 M _ { \odot } and radii in the range of 13 \leq R \leq 16 km .
We investigate the integral parameters of rapidly rotating stars and obtain evolutionary sequences that correspond to constant rest-mass stars spinning down by electromagnetic and gravitational radiation .
Physically new transitional sequences are revealed that are distinguished by a phase transition from nucleonic to color-superconducting matter for some configurations that are located between the static and Keplerian limits .
The snapshots of internal structure of the star , displaying the growth or shrinkage of superconducting volume as the star ’ s spin changes , are displayed for constant rest mass stars .
We further obtain evolutionary sequences of rotating supramassive compact stars and construct pre-collapse models that can be used as initial data to simulate a collapse of color-superconducting hybrid stars to a black hole .
