Main results

In Z. Zakir’s interpretation of the Oppenheimer–Snyder dust-star solution in Schwarzschild coordinates, the stellar surface asymptotically freezes outside its gravitational radius, while the internal layers freeze near their own asymptotes. The resulting gravitationally frozen object is termed a frozar.
